Okay well I haven't tested positive for anything yet, although I have been tested.

I went to my doctors to state that I haven't been feeling my normal self after sex with a certain girl.

Doctor was comforting me saying I'm a very young healthy guy, who's been tested for STI's, he was also stating there are thousands of people out there who have never ever even been checked and could have it, that made me feel a bit better.

Something that did worry me about what he said was, there's always the possibility that "things" could be caught and transmitted that health medicine doesn't even know about and has never been diagnosed.

Somethings wrong and I dunno what.
