I have intrusive thoughts

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?

Any one else deal with this? Like from the moment they wake up to the second they fall asleep, the intrusive thoughts are there?

I been dealing with OCD my entire life but recently I been finding it really difficult to find the slightest relief. I know it’s not good to do but I been trying not to think of the thoughts but of course they come back even stronger. Does anyone know what I could do in the meanwhile ? Thank you
