I was having sex with an escort, who on a local board, has positive reviews. I have had sex with this escort three times now. However, several hours ago, I had sex with her and while wearing a condom, I felt blood trickling down my penis and into my testical area. She says she is clean, and that she doesn't get periods (she mentioned why but I didn't pay attention to that). The condom stayed on the whole time, so I don't think blood got in anywhere.
Since the blood touched parts of my genital area, am I at risk for std's/hiv (chlamydia or gonorrhea)? In general, does blood coming out of a vagina transmit std's? Thanks.
