The act itself is one of the most erotic sensations, provided no one has any major hangups. Most guys will never admit to a friend they enjoy pegging. I wouldn't dare tell some of my mates as I know they wouldn't understand, it seems to be a taboo issue with hetrosexual men. To me its not sexually orientated, its an act of physical, sexual contact, I would not class my self as gay or bi-sexual as I'm naturally attracted to women, I have had sex with men, if not for the anal side I just dont get off on men.
I get off on being penetrated, and having my prostate loved, and the sensation of being filled.
Try it tough guys I reckon most who try it will like it, and alot will fight liking it, and most would never admit to it.
