So, I'm going to meet a girl tomorrow (whose been with quite a few guys,) something will happen tomorrow (possibly BJ, HJ after a make out session.) It will most likely be a one night thing and I will probably not see her afterwards, so I was wondering: What can I do to minimize possible STD risks with the above mentioned activities. Can I minimize those risks to a point where the risk is almost nil, if so, how? Should I be worried that I will contract anything from one encounter? Thank you all and I really do appreciate your help!
