How on earth would any sort of sex with a girl make you gay??
And honestly on top of that, I actually believe that guys can have sex with other guys and still consider themselves straight. That's all just physical and if you do what feels good or if a body turns you on, sobeit.
But, to me, only guys who can truly be satisfied and happy being in an actual relationship with a guy (as in sex with a guy meets all their sexual needs and their emotional needs can be fulfilled by another guy) are gay.
If you can only say that of a woman, and not a man, then you're straight.
And, for those few lucky ones out there who can say that for both men and women, they're bi.
Everything else is just sex. It's fun, and if something turns you on, you do it (makes penis happy).
Some guys are not the slightest bit turned on by even the hottest guys. Some are not the slightest bit turned on by women. Some are turned on by both, and others seem to be turned on by everything all the time. To me that's more sexual function than it is something within your psyche. Regardless of who you fuck, only you deep down inside can say whether you are gay or straight or bi or asexual or whatever.
Take me, I find some women very attractive. I think huge fake tits are one of the coolest things ever, and I find female bodybuilders and fitness models with ridiculous high spherical fake tits on a tight muscular body with some big bimbo cock-sucking lips to be a HUGE turn on! Do I want to have sex with girls like this?
Maybe, probably, but I'm not totally sure if when the moment came I'd be up for the task. Would I love to go all crazy full body oral on a woman like that? Yep! (although a hot trans like that would probably be more a better fit because vagina just looks like a weird mix between an orchid and an alien).
But, could I spend my life with one or feel right being in a relationship with one or forego sex with a man while with one? No way! So I know I'm gay.
