Hiv thu underwear

Happen last night this male and myself got together and he had his shorts on and his underwear on underneath his shorts ,according to him and i was just in my underwear regular white cotton . I sat on his lap with my back to his chest. He got hard and started pumping his **** into my actual anal area through his shorts and my underwear.  He did this for about 25 minutes.  When i got home checked my underwear and notice a spot my underwear by my anal area. I had bled from my anal two days before. This look like a Wet spot from the humping. Since he was in my anal area through my underwear and his shorts  am i at risk to contact HIV is his precum pass through his short to my underwear and into my anal through my underwear .  Please advise what my risk is

So even though his precum passed thru my underwear and his precum actually made contact thru my anal entrance for about 25minutes thru my underwear first, of course, there is no risk at all.  Thanks for your reply
