Hi- I slept with a girl 4 days ago, no protection, and have been freaking out since. I went for STD screening and Dr told me I wont know till Tuesday and even that isnt trustworthy since I went so soon after my encounter. It may be paranoia or it may be a problem, but the tip of my penis has been feeling wet and cool ever since. There is no pain and no discharge. Just a wet and cool feeling. Does this sound like a problem?
