Today I had protected sex with this woman, which was a sex worker. At first we had protected sex and it ended the session with protected fellatio. Now i wasnt sure if she washes her mouth afterwards, but at the second sesion, she gave me UNPROTECTED fellatio, and then we continued with protected sex. This concerns me because i just realized that she probably didn't wash her mouth after the protected fellatio, which means the vaginal liquid was definitely still in her mouth. Since she gave me unprotected fellatio afterwards, does that mean im at risk?
