I'm a 17 year old male in perfect health. A couple weeks ago I was experimenting on how to achieve better orgasm, and I found that rubbing my bladder area with moderate pressure right before ejaculation made it much more interesting. About 4 days ago, I started having the urge to urinate very often. I have been making about 9 trips/day to the bathroom since then, and often the urge comes back within half an hour. The urge is worse when I am sitting. I never been sexually active so an std is out of the question. I have no burning, back pain, constant thirst or any other unusual symptom. I am wondering if the bladder area rubbing has anything to do with it. Is there concern for me to visit the doctor? Any opinions would help.
