what do i do from here? how unlikely is transmission to genitals? is it risky to continue what we’re doing?
I only just noticed it on my boyfriends finger (conveniently his right hand, middle finger the exact one he uses on me). i don’t know how long hes had it but hes touched me and fingered me multiple times a week and we’ve been dating for 4 months now.
