I am a straight man who enjoy erotic massage much.
My exposure is that every time I take the massage, the girl touch every part of my body with oil, genital area, nipple, everything, and sometimes with her fingers insert in my anus briefly (1 inch deep I suppose). I have never had any kind of insertive vaginal, anal or oral sex during the massage.
My understanding is that body massage is a safe sex activities. But my worries starts coming out of my mind I am not sure whether her hands are clean and not stained with any blood or semens from other customers. If she massaged me right after another customer immediately, then I am susceptible to transmission if my body have some cuts which may not catch my attention.
Is there any risk of transmission this way?
