Absolutely - you just get a vibe..
There are some that are as you state respectful and appreciative… a look and smile a little sense of intrigue and a noted interest.
A shared connection of sorts.

Others just seem invasive and abrasive.
Leering and pushing into your space uninvited our socially awkward to a fault - they just don’t take negative queue's that it’s too intrusive, move on by already.

For the most part the the beach regulars manage some of that - and are pretty protective of the single ladies for sure.
I’ve seen them step in and move people along.

One maybe uncommon turn on I can share is those girls who are a bit shy removing their dress to reveal their swimsuits at the beach.

Recently, I saw a beautiful woman (maybe mid 20s) look left and right before undressing to reveal her brown string type swimsuit. Her girl friend was smiling the whole time. She is slim with a perky butt. She looked back to me when she realized maybe she showed too much (butt crack) as she adjusted her bikini due to the waves.

Quite simply it's a girl tying up her hair into a ponytail. Drives me wild every time.

That's how my first experience of receiving oral started and it has stuck with me.

Porn Store
 

Saw a picture on OCC that created a new fantasy. I want my wife to poss for a mature wife magazine and get posted. Think Readers Wives. After it is posted and distributed in porn stores, I want her to poss, nude, with a copy of the magazine in her hand, opened to the section she is in.

I actually think that a nice toned stomach can be so fucking hot. The girl can be completely fully clothed, but if she's wearing a small/cut-off top that shows off her stomach, it can be an immense turn-on for me just to see the stomach alone.

Wow very hot
 

Wow that is such a hot fantasy, to bad internet somewhat crushed it.

My wife talked about being in a men’s magazine back in the 80s and 90s.
An erotic fantasy of hers but never it never happened. That’s why she is posted here on OCC for others to enjoy.

Posing in a porn store nude with her magazine I am aroused thinking of the event.

New one to add to my list.
I bought my wife a womanizer toy few weeks ago.
She really loves the toy which can make her orgasm in no time.
The thing that really turns me on is her facial expression.
Never saw her enjoying herself so intensely.
Maybe when I lick her pussy, but then I can see her face.
So last few weeks I have been turned on by just looking at her face while using her toy and reaching an intense orgasm.
