I had sex for the first time with a massage girl using condom, she used one condom for bj and later used second condom on first one so I had sex using two condoms at same time for less than a minute. She said she is safe and then i started to fully penetrate her. My doubt is what are the chances of HIV/STD, as STD can transmit from infected person to uninfected person through mucous membrane. If the uninfected person has no cuts or open lesions and used condom can he get STD?
