Bisexual or HOCD?

Im a 20 year old guy thats been suffering with HOCD. Ive never been attracted to guys before. I never check them out in public like I do with girls. Ive always liked girls. Ive been doing nofap because of the benefits i heard it has on HOCD. I was on my 4th day and relapsed and I had some gay thoughts while I was in the middle of it and I mightve liked it but im not sure. I feel like Im denying it. That same night i got drunk and whacked it again and I got more gay thoughts and i started thinking to myself to just accept that im bisexual. The thing is Im not attracted to guys. The only time I think i am is when im masturbating. I dont want to be bi I want to be a man. I hate having these thoughts I feel so fucked up over them. The more I think about it the more I feel like im starting to like them more and more. Its making me depressed. I feel like less a of a man over this stuff. I was going to talk to this girl that I really like but its making me feel like I dont deserve her that she deserves a real man. I use to watch alot of porn previous to starting nofap I feel like its fucked with my head. I liked some hardcore stuff but nothing illegal or fucked up. I would masturbate alot too. Do I sound Bisexual? Is it possible to turn bisexual? Should I see a therapist?
