I have heard many times, also from the doctors that mutual masturbation is safe, and is zero risk, even with small cuts.
My question is... at this site it says "The most common examples of such questions are those about low risk exposures to HIV, such as oral sex, condom- protected intercourse hand-to-genital exposure, and nonsexual contact with possibly infected blood or body fluids as well as symptoms of early HIV infection." at the top on the expert-forum questions. Here it refers to hand-to-genital exposure as a low risk..? why?
