Hello. My friend had sex with a sex worker recently. He said he touched and rubbed the woman's outer part of the vagina and clitoris with his fingers. Then while wearing a condom, he by mistake touched the inside of the condom with his fingers. He then wore the condom and had intercourse. Now he is worried whether he has a chance of getting STD or HIV because of that finger contact? However he had not inserted the finger inside the vagina.
