You sound exactly like me when I was younger. In retrospect, though, it's hilarious how much emphasis I put on being "normal." The thought of me actually achieving that is preposterous.
HOCD is better than POCD, I'll tell you that much! But seriously, is it the stigma behind homosexuality that you're afraid of, or the practical issues? Because OCD is probably more of a threat to your sex life than latent homosexuality.
You might be autistic or something, you never know. But PDD is being massively overdiagnosed right now because the definition is becoming more broad. I had a therapist who was constantly trying to fit me into that box, and it drove me nuts. I wouldn't want to push someone to get tested unless they were a textbook case, since it's expensive and can't be treated.
