I used to say no, then I found out an ex had lied about his previous sexual partners and got paranoid about STDs (I didn't have anything, I just worried unneccessarily). So I looked them all up. I think the problem is most people think if you have unprotected sex with someone who has HIV, you will instantly get it. But the chances are much, much smaller than that. Obviously if I had an HIV positive partner I would use protection. But if there was ever an accident, there's now a tablet you can take afterwards.
I just think if I really liked someone, I don't think I would instantly give up on them for having HIV.
