STD contamination fears

I’ve been feeling the urge to avoid intimacy or purposefully engage (for reassurance that I won’t give into a compulsion) because of intrusive thoughts and fear that I’ll “check/test” my reactions. My OCD is making me so scared that I’ll purposefully think of a child and try to see if I like it. It’s so complicated but I guess I’m mentally checking if I would mentally check during intimacy. I’ve even envisioned myself checking and it’s making me so nauseous. I know it’s a compulsion like any other but the sound of “touching yourself to the thought of a child” sounds atrocious and vile. I’m terrified I’ll automatically start checking next time I am being intimate. I truly feel so worried. If anyone has gone through something similar, I’d appreciate hearing your experience. Or if anyone has any advice?

Trying not to seek reassurance, but rather connect the dots on my OCD and possible reasons as to why I am the way I am. I have severe OCD (or at least I hope I do) mainly surrounding POCD. I've had symptoms of OCD the majority of my life but this theme has come up more recently. When I was a kid, and i'm talking 6-7, I was first exposed to some really gross adult content online. It was introduced to me by a friend of mine around the same age of me. I saw some really disgusting things that a 6-7 year old should definitely not see. This was not a one time occurrence, as I had been exposed to taboo topics online years to come after that, such as the same friend introducing me to Omegle... And i'm sure you can imagine how that went, theres a lot of genuinely disgusting human beings on there. Coming back to the reason for making this post; is it possible to early exposure to this content could be one of the reasons I struggle with POCD? It genuinely scares me to death because you hear that real p*dos dealt with simular situations when they were kids, so thats kind of making me feel that this could be more than OCD, and I could be a genuinely bad person. My POCD feels so real, that at times i'm fully convinced its not OCD. Sometimes I can't even distinguish the feelings of attraction between a younger person and an older person, except for the feeling of anxiety and fear. Its really hard to explain without going into detail, but it just feels so real. Some feedback on this would be great, thank you all.

back in october i made my first post about my specific type of ocd, how it mixes in with my day to day and how i “deal” with it. i talked about the starting point, how it gradually got worse, and then how it was going just a few months ago. i always think it’s insane how much can change in just the course of a small to a large amount of time. right now, i honestly feel like garbage. to be quite sincere i really want to give up, i’m barely holding on by a thread. and if i cut that thread, i really doubt anyone would care. i’ve never considered myself to be a suicidal person, and i still don’t consider myself that right now. it just gets to a point where it’s just, a lot to deal with. i don’t really enjoy things a lot nowadays. sure i have good days like everyone does, like today, when i was just enjoying my day without worries. but then it all comes crawling back twice as bad the following days. i take online college so i’m usually just stuck at home most of the time. but, when i do decide to actually go out and leave my house, my ocd just explodes because i have this whole routine i need to do or else i feel like i’ll contaminate wherever i end up going. i’m not going to go really deep into my compulsions because it’s hard enough to live with them, much more having to type them all out in detail. but when i go out my compulsions go from wiping down all my stuff i’m going to use after showering, to washing my clothes/cleaning the washer + dryer. i also have separate things (or two of the same thing) i use specifically in my house, and items i use when going out. such as shampoo/body wash, deodorant, lotion, hair curler, etc. as if that’s not draining enough, i also feel the need to fast a couple days prior to any plan i make because i’ve forced myself to believe i need to feel empty in order to be clean. i’m not sure if that’s my past eating disorder talking, or my ocd, but my brain can’t help but think any food in my house is utterly and completely contaminated. i’m so tired of this feeling, feeling like nothing will ever be clean again. feeling like my ocd is trapped in my childhood home. feeling that wave of diseases rushing through my veins the moment i step foot into what’s supposed to be “home”. and i’m so scared of therapy because what if i do get healed, and then everything comes rushing back the second i step into my room. i’m planning on moving somewhere far from my current house in this next coming year, so sometimes i feel like just waiting it out. but it’s insufferable when going to hangout with someone. i miss my friends, my family, and my partner. it’s crazy to me that i’m dealing with all this at the young age of 18 but, i’m sure lots of people have it way worse. i just want to find a way out, any possible way. but i keep pushing myself deeper and deeper that when i finally find a way, it will no longer exist.
