What are the HIV chances in this scenario.

So I met a guy, he did show me his test results, all clear. We did not have penetration. Only side and kissing. But I noticed rashes on his chest. Just all together in one place.

I did not think much about it, but today randomly browsing the net trying to educate myself, I realized some of the rash pics related to HIV matches his.

There was no anal, the only thing I personally came in contact was his cum. I was clothed, but maybe came in contact with it via penis tip if it seeped in. Not sure tbh!

It’s been less than 74 hours still, should I go get PEP? I am kinda paranoid.

Can anyone advise?
