I've had boyfriends back in high school, althought I know that I've always been attracted to girls. So yea, I've tried being in a relationship with guys but they never worked out. I never really imagine being emotionally attached to guys although I'm still attracted to them. On the other hand, I always find myself being emotionally attracted to girls but never imagined having sex with them.
You will probably have better luck in the Sexual and Romantic Orientation forum, this one is for talking about your gender. Have you tried imagining yourself having sex with girls? If you have and you don't feel much, it's possible you're heterosexual, but homoromantic. That is, you like having sex with guys but don't fall in love with them, and fall in love with girls but don't want to have sex with them. It's actually possible for them to not be to the same gender. It's also possible you will find you like having sex with girls when you're dating one.
The staff have moved your thread over to the Sexual and Romantic Orientation forum, where you will hopefully get some more replies!
It's hard to tell, but I'd say you were a homoromantic heterosexual (if you want the specific terminology) (Feels sexual attraction to men and romantic attraction to women) Obviously you're the only one who can say what you feel for sure, though
