A few nights ago I did stuff with a guy. He rimmed me and pushed his penis near my anus, sort of fake sex if you will (as i didn't want to have penetrative sex at this time) and around the general area, close to but definitely not penetrative. We also did a bit of finger play but again, none penetrative. I was worried about this so checked with tissue to see if I had any blood around 30 minutes afterwards and I couldn't see anything, although even though I was somewhat drunk i'm still quite conscious about safe sex etc (which we all should be!). I did rub a little but nothing seemed to show, good sign, didn't think I had any cuts.
the next day I felt a little sore, and it was sorta red but didn't think anything of it. I checked AGAIN if I had a cut or anything with tissue (just incase) and I did not, however today I've noticed its much more sore and irritated and now I've started to bleed a very small amount if the area is irritated. I'm wondering if this is due to his saliva, could this cause a reaction? (I do have sensitive skin, always have done)
I'm sort of worried that somehow his teasing may have torn somewhere outside my anus, and worried I could have contracted HIV or anything with his precum? To the best of my knowledge he didn't ejac on me. I also don't really remember any pain taking place during, perhaps a slight scratch from a fingernail but not enough to cause a scene over. Was I at risk or is this highly unlikely?
