I'm gunna try to explain this as best as possible...my girlfriend and i have a healthy sexual life. Neither of us have had other parteners and neither of us have any std's. Every now and then if it's been a while or if we are just feeling in the mood we will have a "long night" and have intercourse of some form in a row. After this I've noticed that I get a sall pain in the end of my penis and the feelng that i need to urinate, i usually do end up urinating but afterwards the pain is still there and i still feel like i nee to pee. Is this pain due to ejaculating more then once over a relativly short period of time ? The pain usually goes away after about 20 minutes and i feel fine and totally regular.
