So there are a few thousand posts on a topic like this, and I have read many of them, but admittedly not all, so my apologies if this is a repeat question ( which it probably is) - So I was at a massage parlor, and as part of the massage 'extras' I fingered her for about a minute and then within a minute, used the same hand and fingers ( without washing) to masturbate myself to completion. I know the HIV risk is close to zero, but are there any other legit STI risks that I need to worry about? I have a long term partner and do not want to put her at risk. I know from Dr Hook and Dr HHH posts that this is what they call a low risk activity, and I wouldn't normally worry, except for the part where I used the same hand. Please advise ! Thanks
