Gay porn only? Question..in the closet

For years now I've been watching gay porn more than straight porn... what I'm confused about is I can't get turned on by a man in person and not just that but the idea of kissing or sucking or even really touching is really not even close to a turn on... accept ass fucking or getting fucked.. which I only tried once.. but my problem is I last for HOURS and he never did. Women always can.. So if I wanna try this, any advice on how to find a man who can last who doesn't like the other stuff. I've only tried once, then I realized I could probably try 100 men and not get satisfied by any of them.I also would prefer for no one to find out because I prefer women and just don't wanna deal with it
