Dating app and possibly pocd

POCD,+18 please, need of help I keep thinking abt when I was like 17 I used to go on amino to roleplay ships I like,and I'm freaked out now over it because even though I never did sexual rp before I still did rp that was in a romantic setting and I'm worried if anyone I ever roleplayed with was massively younger than me and I just didn't care or didn't put in effort to notice. I have a memory of doing a short roleplay with someone and feeling uncomfortable about it and i don't know if it was because I just felt shy or they were young and I was uncomfortable but doing it anyways. A long while back I went to the amino again and checked all my followers and tried to find who I roleplayed with going off of what I remembered their pfp being and the one I thought seemed most similiar was someone who was 20 and all the rest didn't list their age but im worried what if they unfollowed me and did say their age. It all makes me freaked out because there was this thing where a 20 something dude said it was OK he roleplayed nsfw w minors because he didn't want to seem rude by saying no when they suggested it and I don't want to be as bad as that guy is and i never did anything sexual but I'm still scared it's just as bad if it's roleplaying a romantic relationship and I had that memory of feeling uncomfortable but not wanting to seem rude by not interacting. I dont know if it's a false memory or not and idk if it is. I just know when I was spiraling and checking all my social media I deleted a chat w a ship rp w/o checking and I've been freaked since.

Yesterday I was watching a show and I thought the boy was cute and just randomly texted my cousins cuz we were watching the same show. I’m 23, & at first glance I barely paid attention but I thought he was at least 21, but my cousins replied with “he looks 18 you pervert” or “it’s looking bad for you”. I started freaking out immediately checked to his face properly again and he did look younger, & I felt so disgusted with myself. I felt terrible, instantly regretted everything & didn’t know what to do. I’ve been anxious since last night barely been able to sleep cuz I just complimented someone who is younger than me. My mind is now like ruminating that I’m a pedophile or pervert for thinking that. I hate this because I honestly wasn’t thinking of it in that type of sense like I would date him or something, I was not aware. I would’ve forgot about that moment after. I needed to get it off my chest cuz I have been feeling exhausted & terrible.

Right now I'm dealing with Pocd, and my main obsession is like age checking ? Whenever I see someone somewhat attractive I always have a thought saying "what if they were underage and you found them attractive " do I just dismiss the thought? Because it really does bother me but at the same time I'd like to know. Or one time some girl appeared on social media to look older and I found her attractive but once I saw her age I freaked out & felt so uneasy and uncomfy.
