Intrusive thoughts on making sexual advances on same sex friends <<<<<<<

I need advice for intrusive thoughts. I used to feel like I could handle them. They weren’t nearly as bad as the things that related to my actual life. But now, I’m suffering. I haven’t had a sexual experience in over a year that didn’t involve constant intrusive thoughts. Most are somehow related to kids and I keep chasing off the thoughts but it’s so bad. I know you’re supposed to ignore them but I don’t know how I can just ignore that and continue what I’m doing. But they’re coming on stronger. I had one earlier I could not get rid of just as things finished so the thought came on strongly just before my orgasm hit and now I feel absolutely disgusting. I hated the thought and I know it’s not me and it was not enjoyable but it still feels like I was getting off to it. I feel sick. I’m so fucking tired of these thoughts. They’re in my every day life too and it’s all the time. I just want it to stop but ignoring it feels so wrong. What should I do?

I remember another thing from the past where it was a sexual thought and I don’t remember if I was talking to or dating my gf at the time but it was like “if I was talking to someone else like _____ I’d be able to have sex already” and I feel terrible bc I don’t want sex. I would rather be with my girlfriend than any other girl. Idk if the thought was intrusive or not. I think the people or person I was thinking of may have been intrusive. I’m just terrified bc I really love my gf and don’t care about sex

Does anyone else get intrusive thoughts of same sex oral sex? I’ve been struggling with this repeated intrusive thought for over two years, and everytime I get it it’s like a stab in the chest, I hate it so much if I think about it for too long it makes me feel sick and I’d never want to do it so why does it keep coming back 😔
