I am a man, and I recently had an encounter where I received oral sex from a stranger at an adult video theater. This is the first time I have done this. I never spoke to him so I don’t have any sexual history from him, however given his behavior I would consider him to be “high risk”. Immediately afterwards I went to the bathroom and I smothered my genitals in Purell hand sanitizer. Then I urinated and washed my genitals in the sink. However after reading online it appears that there is a risk of contracting herpes, gonorrhea, and other STDs even though I was only on the receiving end. I am especially concerned about herpes since there is no cure. My question is, what kind of risk do I face? and did the urination and sanitizer do anything to help prevent it? I have a fiance that I do not want to pass anything on to.
