A couple of nights ago, I had unprotective vaginal sex with a HIV + partner, who the last time I checked, levels were undetectable. He did not ejaculate inside of me but preejaculate may have been present. The next morning my menstrual cycle arrived which scared me further. I went to my local urgent clinic and was prescribed Truvada as PEP. Did I overreact in this situation? Fear is a great motivator and the Internet has the power to invoke fear regarding HIV. Infection from preejaculate has not been studied in great detail but there have been reports of infections from preejaculate or HIV present in preejaculate. I wanted to be safe than sorry.
