Cleavage. 100%. Any flash of any cleavage at any time gets my attention
After that, it's watching woman in various situations and trying to work out their bra size

Catching my eye
 

For me, well anything! Depending on her position relative to me. I love seeing her ass in tight pants, her long legs, her slight peek of cleavage as she leans forward, a bare belly, the way her pants hug her pussy, the nape of her neck, her smile, her eyes...
Yeah, I absolutely cannot say any one thing. I like the whole package, no matter what part is right in front of me!
Any woman who is wearing tight fitting clothing that shows off ANY part of her makes me quiver with excitement. Young, old, slim, heavy, tall or short. I want them all! Tee hee hee...

Mad magazine's mascot, Alfred E Newman said one time “the first thing you notice about a woman, depends on which way she's walking ”. Truer words were never spoken for me.

I love seeing back muscles. Not overly muscular, but just a bit of tone. Showing off the back is really sexy to me, and to see some definition is hot. I think it has something to do with TV I saw growing up, where all you could ever see in sex scenes was a naked woman's back.

Woman's body, mind of a child
 

My husband says:
She was pretty til she spoke

Yep, we had one of those in the neighborhood. Single mom, smoking hot, didn't talk much. Then one day her true colors came out. No matter lovely her physical appearance, it was all wiped away in an instant.

It's always the ass and legs for me. It's mesmerizing to me... like it's all I want to stare at on a fine woman. In fact, 99% of the pics and vids I save from the net are exactly that. It could be something as simple as a woman wearing only a thong shown walking, from a low angle, of course.

There was 1 girl I was so smitten with back in college, and her legs and ass were out of this world; they were shapely with some muscle since she ran track and was a pompom girl for a while years prior... sadly I was destined to only be in the classic "friend zone" with her (:(), but damn I could not stop staring at her perfect legs and ass... I still get hard just remembering. She knew how I felt but I doubt she knew the extent of just how much I fantasized about her and those incredible legs/ass she had..... goddamn she was somethin' else. I remember one day hanging out with her in the dorm lobby and she had denim cut-off style shorts on....oh my god that visual...

Living in Japan it’s teeth!
There are pretty women everywhere, but mangled smiles are more common than they should be.

Otherwise it would have to be breasts. The wife reckons I do it without even realising. I told her that’s called being a man. We can’t help it. Biology is hard to deprogram!

For me it is two things:

1. Tits, I especially love to see a woman with big tits going braless. But any sized female with pokey nipples is just fine.

1a. If wearing a bra, I love to see cleavage. Two big ones pushed up together makes for a mighty fine view.

I’m exactly the same. Whenever I see a women in public, the first I try to see if she wearing a bra. It’s like instinct. And I see she’s not, it immediately gets my attention.

Am I the only person who comes back to this thread and each times he reads a post thinks, yeah, yeah, no matter what the content.
So I suppose the answer to the OP's question is everything!

Thinking about it I suppose it's a question of availability because in the winter, the ladies are all wrapped up with nothing on view, and then, you see a lady in a skirt, doesn't have to be short, but there are legs in tights or stockings and that catches your attention because it's a treat in the famine.

Then spring comes along and you see more legs but the clothing gets lighter and there are tight jeans, perhaps a bit of cleavage.
When summer comes , you take the light dresses for granted and just wonder how much they are wearing underneath.

It also makes a difference if you are in a princial town or a city because I think there is always more to see in a city.
Although in the summer by close to the beaches....
Ok, I'll leave it there and won't talk about beaches.

So I am not the only one? Whew. (I seriously thought I was the only one. I need a new type of friends, I think.)

Was thinking the same thing... But there are probably many people I know who may think the same way, but do not let on to others that they do.

It’s a special skill that people like us have. We are like the Jason Bourne of tits. Put us in a big room of women and we can spot the ones without bras in 5 seconds.

This is what I like to see. My wife loves to give a little flash now and then.

What catches your eye?
 

Provoking eyes, sensuous lips, a charming smile, voluptuous hips and legs in a flattering summer dress, feminine wrists and ankles, well-proportioned pedicured feet, lickable soles, a noticeably curved bum with presentable anus, a natural hairy muff filled to the brim.

Well this View is obviously from a woman's perspective. I like guys who dress well and that doesn't mean flashy. They can dress casual and look really nice. I don't like skinny jeans on a guy. I don't like man buns. Now with that said I like a guy with a nice ass, it's that funky hairdo on top that's a bit of a turn off. I like tattoos but not excessive and I think tattoos on a person's body should tell a story of who they are.

I like guys who are taller than me and I'm 5 foot 7 and 1/2. That's not totally necessary but it is a preference. I like guys with confidence without being overbearing. I really have not had much success with gamers and I am talking about hardcore gamers who are on there machines for a day or two at a time. I think real life is more interesting. Maybe that went too far but once I get started I couldn't quit. LOL

Here's one from a wife's perspective:

We were traveling east to Denver and spent the first night in Reno.

After dinner we hit the Hotel bar and then the pool. My wife was in a really fun mood.

She was in her mid 50's at the time and at 64 is still unbelievably hot. Not just to me but to the younger guys who always flirt and occasionally make passes at her. At 5-8 and 128 pounds, a weight she works at all the time with tennis, swimming and aerobics she is a mix of Denise Austin and Annette Benning, yes gorgeous.

We stood neck deep in the pool water and watched a young guy go in and out of the pool constantly. I asked my wife what she noticed about that guy. She said, he's got a great ass.

Really I asked, you look at butts first? I always have.

The guy got into the hot tub for about five minutes then walked by us three or four times. He had one of those real clingy swim suits on that stick to your anatomy. He had a huge cock outlined in those wet shorts, big enough he tucked it sideways onto his hip so it ran six or seven inches at a right angle to his hanging nut sack.

Nice package my wife said, but I still like his ass. It was evident the guy had left the pool for the hot tub to get rid of shrinkage and was trying to get my wife interested in his huge cock. I expected him to pull his shorts off at one point before he finally gave up.

It was nothing new, she's been flashed, had other guys have their cocks fall out of there shorts or swim trunks "accidentally" many times. She's always amused.

I didn't know you were an ass woman I said. Who has the best ass you've ever been with? The type of question that usually generates an awesome story.

She thought for a minute then said, Doug. I had actually known Doug, he was a little guy, about 5-7 with a lot of body hair. One of those guys that has a forest of hair on his neck just below the shaving line. I knew she'd sucked him off a few times and that he'd fucked her a couple when she was about 21 but that was it.

Really Doug I said?

With her usual impish grin she said, you don't want to really know do you? Of course I did, tell me about it.

Well he's one of the few guys that was shorter than I am, you know I like tall men. Doug was built, real solid muscles and he had the sexiest chest hair, a forest you could get lost in, I love chest hair.

I remembered Doug as a V-shaped guy, sort of a gymnast kind of build.

It was dark the first time we did it. His cock wasn't huge, maybe 6 or 7 inches and after I sucked and swallowed him it shrank down to less than 3, I wasn't that impressed. But then he turned on the light and walked into the bathroom and I saw that gorgeous ass. Yes it was covered in that same chest hair but his ass cheeks were perfect and I had to taste it.

Taste it? Yes, he turned the light off when the came back into the room and I told him to turn it back on. His cock just pointed straight out, not long enough to hang down but it wasn't his cock I was after.

She told this story loud enough for the young guy who was still in the pool area sitting on a deck chair to hear. Yes, I noticed him getting hard and swelling his trunks.

I rolled Doug over, told him to get on his knees with his head down and started to lick that incredible ass. His cheeks were like rocks. I would have sucked him from behind but his dick was too short. I reached around and jacked his cock as I licked his ass and he shot big loads of cum all over the sheets.

I licked his ass every time after that before I sucked him or let him fuck me. He wanted doggy style or me on top, no way it was missionary with Doug, so I could grab that ass and hang on.

Did you cum I asked her, knowing she usually needed at least an 8 inch cock to get her off.

Yes, multiple times, I just couldn't get over that ass.

The young guy stood up and walked right next to his and pulled down his shorts. He was at full attention, rock hard and at least 9 inches long with long hanging nuts. He looked straight at my wife and I thought she might give him a chance but instead said, that's nice dear. Thanks and turned away.

"L." with Those Legs...

My old college friend again that I mentioned on the previous page (the one that I was really head over heels smitten with)...there was another occasion where I was in a computer lab, and noticed her outside walking up the side towards the building.... just my luck I happened to look out and notice her as the wind blew her long wrap skirt OPEN. So...the visual was that I went from seeing nothing to seeing to her entire right leg suddenly being on display...and again they are track or gymnast-caliber legs and ass which is insanely hot to me..... the sudden exposure and her "oh no!" reaction to it (frantically reaching down to close her skirt) really hit me; I exploded all over myself in literal seconds.(while trying to maintain composure due to being in a room of people, lol) Besides those times when she was performing as a "pompom" girl at a game, it was the first time I got to see that much of her....so this visual is etched forever in my memory, basically. It would be the first of many nights I'd later have one hell of a jerkoff session thinking about that absolutely incredible set of legs and ass on her. haha, there would also be a day when I stole a pair of her panties; she made the mistake of trusting me to watch over her laundry basket while she pulled the car around.

It's unfortunate that most other girls I knew or knew of at the time couldn't even begin to compare in that category....not even the girls on our volleyball or track teams(!), and unfortunately I never met any of the girls from the tennis program.
