Hello, I really don't know if the topic of this is chlamydia, however, I don't know what is going on with me. About 2 weeks ago I had unprotected oral sex performed on me (I am male) and I have noticed that the tip of my penis has become very sensitive. It was never this sensitive before, so I am thinking it must have been from the oral sex. In addition, I notice that when I urinate I feel a little warmness/burning sensation. Its not at the point where its painful, but it is nevertheless uncomfortable and bothersome. I would like to know if you think this could be any type of std? And what should I do to check this out? I am away at college in a different state, so I can't even go to the doctor to test me.
