really confused please read (hookup + sexuality?) [18 yrs old]

So I just hooked up with a really attractive guy and I thought I would enjoy it a lot. But the whole time I was turned off. I didn't enjoy sucking his dick or touching him. I only enjoyed kissing him because I could just pretend it was a girl and I also enjoyed him sucking my dick because I could pretend it was a girl lol.I've always thought I would be into this because I love gay porn and I check out guys and stuff.. But when I actually got to do it, I hated it. I actually made him stop and we both didn't cum and he was pissed about it.I don't know what to think anymore and I'm 18.
