I am a married man and occasionally see the same relatively high-end sex worker ($400/hr.) in San Francisco. To be honest, it's mostly for company and we don't have vaginal or anal sex, but occasionally she'll perform protected fellatio on me. I'm not worried about this. However, I recently started performing unprotected cunnilingus on her. She orgasms very quickly (5 minutes) and typically asks me to place my tongue deep inside her (to give you a sense of the exposure). In addition to this, we have done cocaine together (sometimes a lot) and shared straws, but only snorting, no injection. Thus, my question is, am I at risk for STD exposure given these experiences? My general understanding is that unprotected cunnilingus is very low risk of any HIV transmission. Also, I'm not freaked out, but, of course, I don't want there to be an issue with my wife. Thus, does it make sense to get tested? I'm on the fence.
