Hello. So recently i had a CSW come over. At first we didnt touch each other because i didnt want to. I just wanted to watch her. She was fingering herself at first. After i laid down on the bed she began to give me a handjob. I didnt even ask for it. It only last about 10 seconds until i told her i would do it. The reason i am concerned is because she used the same hand that she fingered herself with to masturbate me. I had an open cut on my penis during this time due to a shaving accident. I know herpes dosnt last for more then 10 seconds outside the body but i still worry. Can HIV be transmitted this way?? Or any other std for that matter. Remember that i had an open cut during this event.
