For a few years now, I have had a clear discharge from my penis. It is only a small amount, but is constant throughout the day. The tip of my penis is frequently cold but not always, but seems as though the clear discharge is always cold. I am 27 and I also began to notice a larger amount of dicharge when I have an erection that I never had in the past. As I read these boards it seems to me it may be pre-ejaculation, but it worries me that something is coming out all the time and it is constantly on my mind. My sex life has suffered dramatically because of this and my self-consciousness. Also, I have been to the doctor regarding this many times including urologists, std tests and all and no answers. Antibiotics have not helped. My urologist says the next step is a systoscopy but he does not sound confident the results will be beneficial to me or my health. I am NOT having that procedure done unless I am assured it will improve my situation. Please help me shed some light on my situation.

THANKS!
