I don't know a single guy that never got excited from somebody seeing his wife Topless or Nude, at least for that first time! It maybe less thrilling after so many times as others have said here? But I don't thing there is any difference if its Live or just showing off her pictures, you can still get excited or turned on knowing others enjoy seeing her exposed!
Like said before after so many times in can be old news or maybe like I found out, I'm paying more attention to some other women that are exposed and my thoughts are of enjoying them at the time instead of watching my wife!
When we went on our 1st Adult cruise with my wife's Busty cousin and her hubby there were things that I found exciting! I was later on getting to the Adult tanning deck with all of them, they came to our room and all left wearing nothing but a Robe cause that's the only thing my wife had on~ lol.
When I finally got to the tanning deck and observed the 3 of them laying on these lounge chair, with my wife and her cousin on the sides and her hubby between them while all were NUDE! I did start to get excited, but at the time I wasn't sure if it was the thrill of finally seeing my wife's Busty cousin all Nude or the fact that the cousin's hubby was right between both of them and he didn't even have an erection or at least a bobber growing? lol
I'm sure he had more control over it then I had, maybe cause they been on these cruises before and he seen plenty of NUDE women on the Cruise or at the Adult Resort Beaches?
But I had to excuse myself and go back to our room, cause I had a erection that would be noticed soon if I didn't leave!
But no matter anyway you do it, I find it still exciting for others to see my wife Topless or Nude, but if they get more Frisky it makes it Better yet!
