I've done it to girlfriends once or twice. It was alright, I'm glad I tried it, but my wife won't go for it, and that's fine, because I can live without that hole. If we were ever to split, and a new girl wanted it, I would do it, but I'm not trying to get it. Now ass play, is another story, I like to lick my wife's ass, and she likes having it licked, and she doesn't mind some finger or small toy play, and that's fine with me. As far as watching it in porn, sometimes yes, sometimes no, depends on who, and how. Gaping disgusts me, if I wanna look in a girls colon, I'll send her to a doctors office.
