I made a mistake again in a spa I visited. I had condom on a she is performing oral. After that I removed the condom as I do not want sex. After some chatting I tried and she tried to put it back on. However, we flipped it multiple times as we do not know the correct side. I am afraid that her saliva during the oral might be the side of the condom that I wore the second time and be at risk of any STD (hiv, herpes, chlam, gono, etc). Please advise.
