Hi. I was with another man. He gave me a massage that turned sexual. He masturbated me. I touched his penis and testacles. I then played with his nipples after that. I do not remember him pre-cumming and he did not orgasm. After playing with his penis and testacles, I played with his nipples and nibbled on them (no blood as I checked with him). I also licked his nipple. I tasted massage lotion in my mouth or tongue and on my lips afterwards. He then shared that he is underectable and on meds. I stopped then. My concern is that I had a 2 to 3 day old canker sore from biting my lip. My hand was on his penis and testacles, and I do not remember there being any precum but now I am scared that my hand with massage lotion may have transferred his body fluid to his nipples that I nibbled on and licked with a canker sore on my lip. I know that a canker sore is not open to the bloodstream. I also have gingivitis but did not brush my teeth since many hours before. Does this represent a risk and if so how much of a risk and should I get tested? If a risk, how is it a risk? Thanks.
