Where do I fit???

Hi, last night at Pride in Perth I had an emotional breakdown when someone asked me my sexual preference. I don't know how to describe my preferences without going into a big long explanation... I get confused and sound vague. When people say 'oh so you're straight' I get frustrated. I don't think I'm straight. I'm not sure if I'm bi though. I need help to clarify 'bi'.
So, my first sexual attractions started when I was a teenager, towards girls.
It was very clear to me that I was attracted to girls. My body would get aroused at the age of 11-12 by images of models in teeny magazines. I didn't really understand at that age that my body wasn't responding to pictures of men... As I got older, during high school, I would get intense crushes on boys... But I was still very aware of my attraction to girls and tried to fight it or suppress it. I was very self conscious about looking at girls. I was so scared of being caught looking at a girl in a way that might indicate I wasnt 100% straight. Fast forward to my adult life- I was with my first sexual partner for 4 years and did not enjoy sex at all. He was a dud in bed but as I didn't know any different, I became even more convinced that I was attracted to girls... I thought that was why I didn't enjoy sex. Turns out, I do enjoy sex with men, he was just crap. I have never fallen in love with a girl, I've kissed a few girls, I've had sex with one girl and it was pretty bad given we both were nervous, drunk and didn't really know what we were doing. During my relationships with men, I fall completely in love with them and the sex is great, but I do constantly wish that I could be sexually intimate with girls at my leisure... I can't of course because that would be cheating. The thing I find confusing is, there is no part of me that wants to be in a relationship with a girl. It's seems to be a purely sexual attraction.
Here's the most confusing thing about my orientation crisis. I love watching gay porn. 2 guys, or 2 girls. Straight porn does absolutely nothing for me at all. I don't know why I'm wired to enjoy gay sex. I love being around gay couples. I love being around gay men. If I go to a gay bar/club I just want to talk to gay men. I think I'm a fag hag?? Gay men don't particularly want to talk to me though and I'm having a lot of trouble finding gay male friends to hang out with. The other issue I'm having is, lesbians don't seem to want to talk to me either, because I'm very straight looking and straight acting.
Is there any category I fit into? Or am I simply a fag hag bi girl who prefers relationships with men? Interested in thoughts please

 

I've never really heard the term heteroromantic before but that makes perfect sense! Thank you.
