I realize there is some degree of risk for HIV infection (as well as other STIs) but am curious as to how risky this scenario seems and whether I should get tested for this and when. Although he stated that he is tested every six months and is negative, and that he has not had sex for a long time, I still do not know him well enough to trust it. I have had receptive anal sex previously and do not think that he fully penetrated me, as I was not in any pain at all. I stopped him, but I am worried that he may have inserted the head of his penis into my anus for about 5-10 seconds. I started feeling pressure and realized he was pushing his penis inside of me. Since I didn't have a condom, I refused to bottom for him, but I ultimately allowed him to rub his penis against my anus.
I had a sexual encounter with another man earlier today and have been feeling anxious all afternoon.
