So yesterday, I hung out with a guy I've known for a few months. We've talked about both of our sexual lives from before, and I am under the assumption there should be no concern. When I asked if there were any health issues, he said there was none; so I was left to not think otherwise.
My concern is, yesterday we performed (man on man) anal sex. This would be my first time, and it was with him. The extent of the activity was no longer than two minutes, and it did not go in "all the way;" past the tip of his penis with no condom or lube. I understand this was completely stupid on my part and I am regretting it fully.
After I felt discomfort we stopped and ended it there. There was no ejaculation, and when I felt his penis before hand there was no preseminal fluid. But, with a full erection, there is bound to be some, but minimal.
My concern is, the next day after I had a bowel movement, I noticed a dab of blood on the tissue and I am worried if there was any possible exposure to HIV. I'm under the impression that because there was no lube, a small tear would occurred, but what are the chances of contracting the virus?
I will be going in for a test sometime in the next month, to definitely check it out, but as for now.. is there a strong possibility I can contacted something?
