And i might also suggest exploring your attractions to women. Nothing made me want to have and sexual relationship with guys. I felt gross and unwanted even though, like you, i had their attention at times.
At first, i was attracted to unavailable women, but i think some of that had to do with not having "come out" to myself yet. I still get attracted to unavailable women sometimes, but it was much easier to be attracted to available women once i realized i was into women. There was a safety in never being able to have that relationship before i came out - i couldn't be gay if i was never able to test my theories because the women i liked would not reciprocate (i grew up in a really homophobic environment). For 3 years i told my t's that i had "given up on men but that didn't mean i was gay" (i wish they would have had me look harder at that sentiment at the time... i guess i wasn't ready and they didn't push). Anyway, i digress. If you are open to the possibility, it could go a ways in helping chip away oat your negative body image. Counseling would also be a good idea. It can be a safe place to talk things out, and there's no judgement regardless of any realizations (be it that you are straight or gay). it can all be really confusing and difficult.
Counseling would also be a good way to work on those body issues...
