Just remember safe sex and no needels. And you will be good. For a guy like you thats carefull. You should never worrie about HIV.
I have received Cognitive Behavioral Therapy for my OCD for about fifteen years now. The best advice I can give is this, even though it maybe sound odd;
Think of your OCD (or particular fear) as a bully or monster trying to terrorize you. You have to Bully it back, tell it that it is nothing more than OCD, insignificant, no more than a thought, mentally beat it into submission, tell it it is ridiculous, stupid and has no basis in reality; This has helped me shrink it down to size. Then take a deep breath, and squeeze your fists when you take the time to put it into perspective, then relax your fists as you exhale and let go of the intrusive thought.
Remember. HIV is actually pretty rare and tough to get. It's just that media uses scare tactics to get us to remember to use condoms. Just always use a condom and you will be fine, maybe also get to know your partners well before engaging in sexual activity. Don't spend any more concern on it than necessary. You will be just fine.
Lastly, consider cognitive behavioral therapy and possibly an anti-obsessive drug like clomipramine, which has done me wonders. :)
Good luck to you, and my empathy to you, as being one who has struggled with this exact same problem! :) I wish you well.
Thanks for the advice Tom! I'll try to keep my mind off of it
