Identifying as a woman only during sex... !?

I’d be grateful if you could share your thoughts about something that has been bothering me for a while. I’ve never talked about this but I need some advice.I'm 22, gay, male and here’s the thing:I’ve always loved straight porn much more than gay porn because identifying with a female is a big turn on for me;Often, when I’m turned on, I wish I had a vagina and breasts;I have a BIG impreg kink: I love to imagine myself being impregnated by a man;I feel REALLY feminine when it comes to sex (or maybe masturbation, since I’ve never had any sex).The point is that I’m absolutely sure I’m not trans and outside my sex life I’m not feminine AT ALL (nor I wish to). I feel so dysfunctional.This also bugs me because I worry a lot that a future boyfriend wouldn’t understand me, since I assume (maybe wrongly so) that other gay men would find all of this a big turn off.Sometimes not being able to experience what a woman does, also makes me suffer. Could this be internalised omophobia? It sounds strange, though, since I’ve always been comfortable with my sexual orientation…In any case, I feel like I’ll never be able to live my sexuality the way I wish to, and I feel sad about that.What do you think?
