Thanks Doc. You are the Best......
Welcome to the forum.
There was absolutely no risk of HIV or any other STD from this event. The skin of the breasts is no different than the hand, back, arm, or any other body part: it cannot be a sourcr of HIV or STDs. And statistically, it is very unlikely your masseuse has HIV anyway -- probably under 1 chance in 1,000. Heterosexually transmitted HIV remains rare in San Diego (and the western half of the US in general).
You do not need to worry, do not need testing, and can safely continue unprotected sex with your wife.
