I think it was when I hit puberty, when it all started. I'm twenty years-old, now. The problem is; whenever I fall asleep, and then wake up, there's always this slimy, clear, sticky, colourless and odourless fluid, that leaks out of my penis.
The look and behaviour of this fluid is exactly like pre-cum. I've had this problem long before I ever touched a girl. So, it's definitely not an STI; however, everything is functional down below. There's no pain, swelling, or any of that kind. When I urinate, I experience no discomfort.
Now, whenever I fall asleep, I have to insert tissues in my pants to make sure I don't get any moist, wet and very sticky spots on the front of my underwear. This problem only occurs during sleeping hours. Only twice, has it ever happened during waking hours.
Oh, and, I've never had any medical problems anywhere in my body. I've never visited a doctor about this problem. Probably because of embarrassment and also because, I'm not in any pain.
After seeing eleven prostitutes in the past nine months, this problem has not become worse, nor has it become less.
