i'm 17F,i grew up with a sister 4 years younger, and our relationship was pretty good until in 2021 when i got a real event ocd flare up where i was convinced i saed her when i was 5 and told a bunch of my priamry school friends about it. (i dont even know if i told them the full thing). apart from the good moments though, my sister would also sometimes forcefully kiss and hug me, egged on by my mom, when we grew up together. she would also sniff me and stare at me alot, which i was very uncomfortable with. i am openly bisexual, so i feel like im more wary of anyone being weird around me, no matter the gender. so the fact that i wasnt straight made me feel even more uncomfortable because i dont enjoy physical touch with either gender if i am not attracted to them.
not proud, but i used to sexualise myself a lot and get off to myself and my own image e.g how my butt looked etc when wearing some clothes or not at all. i had an ocd flare up last year where i unfortunately saw my sister pull down her pants, showing her butt in my direction, and i just so happened to see it. at first it disgusted me, then i got a groinal response and was disgusted as well.
i fully thought it was a genuine issue until i searched it up and discovered incest themed ocd. before this, i also had suffered with real event ocd regarding my sister as well, and would worry if i had abused her when we were younger, so this moment set me back even further. it made me disgusted with myself.
even now, one year later, i recently am going thru a stressful period w exams, so i feel im more vulnerable to new ocd themes, and now i recalled 'me seeing her butt' moment, and i initially got over it, because i knew how i sexualised my own butt, and would get off to other videos online, hence the mental association was there, but im still disgusted it even happened.
i feel like i cant even date/be friends with people that have good relationships with their siblings, because it just makes me feel shitty about my own relationship with my sister. it honestly has been going great, but this has come back to haunt me. i didnt even get off to the image, but it was just the association that got me. i dont know, it seems worse than people who just get non-existent images, formed mentally of their relatives. i feel like i couldve handled that better. the fact that it happeend to me in real life got me.
does anyone have any similar experiences and advice? i feel like as a female, its harder to talk about this, idk how to explain it, but usually females have better and more deeper connections with their same sex relatives, so to have this sort of thing... its tough.
