Hello. My story is a long and painful one.
Before what would come to be known as my OCD descended, I was generally a normal kid; I crushed on girls, and identified solely as straight. Throughout my prepubescence though, a slight homophobia was prevalent in my mind, until I turned 16, in which I imagined a male classmate of mine naked. eventually this thought snowballed into an obsession, and I completely fell off the deep end when I experienced a dream in which I was masturbating to my best friend, only to awaken to a full-on erection. I was terrified. A month later I was sent to the psych ward and diagnosed with OCD.
The next year would be spent compulsively studying and researching about HOCD and homosexuality, desperately trying to create an airtight pool of knowledge that proved with 100% certainty that sexual orientation could not be changed, nor could one be latently gay or bisexual. However, these only fueled the fire more intensely. After testing enough times, I managed to attain arousal from gay stimulus, and the fear eroded at me even further. It made me wonder if I was wrong, and that I was truly gay and fundamentally in denial, repressing my own sexuality.
Hell, one of the definitions of sexual repression is that people have sexual desires, they have sexual feelings, but they refuse to acknowledge them, pretend they aren't real. When their sexual values and sexual beliefs conflict with their own sexual reality, they try to convince themselves that the do not feel what they indeed do feel. I can tell you with a degree of certainty that I have no desire to be gay, and have never really had any romantic inclinations towards men in my life, however my intrusive thoughts remained.
Even worse, it eventually evolved into a "sexual deviancy" OCD, where I began to worry whether or not I was aroused/attracted to young girls. I even entertained a sexual fantasy throughout my teens in which I would masturbate to the thought of my elder sister, which then spiraled into a fear as well. I feel so close to my wits end. In no way do I ever want any of these things to be real. I don't want to be gay, or a pedophile, or incestuous. But does not wanting even matter in the grand scope of things?
I am now 21. 5 years I've been struggling, contemplating suicide almost daily. All I ever wanted was for these thoughts to go away. To be certain, without a doubt, that I am heterosexual, no matter what. That my fears will never be real. That I will never become a sexual monster.
I suppose my questions list thusly:
Can sexual orientation change, even over time?
If I was okay with that sister fantasy before, and it turned into a fear later, does that mean I'll be okay with the other obsessions as well? (POCD, HOCD)
Can one have HOCD and be gay simultaneously?
Why am I afraid to begin with?
Can one suppress their sexual orientation, even down to the thought? (ie. "That guy has a nice ass" "No! No, he doesn't! I don't like guys asses!" etc.)
