Hi I wondered if someone can help me. I'm sick with worry as I'm actually married to my wife. However I met a man for casual fun to experiment. We stripped at separate sides of the room and wanked ourselves and talked dirty. He asked me to orgasm on him and I did so on his chest. He was lying on the sofa and I lent over him to do this. I made sure my penis didnt touch him but I may have touched him slightly with other bits of my skin. He then orgasmed on his chest whilst I was leaving over him. The seamen went on him but I'm worried a bit could have sprayed on me but wasnt visible. There was no other contact. Am I at risk of an std or HIV and do I need to test. As i say I'm sick with worry and also feeling guilty.
