I had an exposure with a prostitute two days before. Both of us are naked and hug each other and slept together on bed. I not sure whether my genetic have contact with her genetic or not but i can confirm i did not penetrated it. After that she gave me massage by sitting on my buttock. With this action, her vagina are directly contact with my buttock. So my question is, will I infected and std such as syphilis, herpes, gonnorhea or NGU and Hiv from this situation? thank you and sorry for the bad english.
