Hello everyone. Im writing because i am concerned over some spots that have appeared on the tip of my penis. They are small, purple spots, mabe ten of them. The skin is completely normal otherwise. I am concerned because these spots appeared about an hour after i recieved oral sex from a girl whom i have never had any sexual activity with before. I have never had purple spots on my penis before, and I am concerned this may be some sort of STD. Please help!
