Masturbation/UTI like symptoms but not UTI?
Hello everyone, I'm an 18 year old male. One night about a year ago, I had to pee really bad, probably just from drinking too much water. And you ever have that where you pee and then you think you're done but more has to come out? Well I had that, but ignored and then went to bed and decided to masturbate. Well I did, and then afterward I had a horrible urge to pee, like I could barely hold it for 5 minutes, and then hardly anything would come out. It wasn't as bad by morning but I still had an urge. I thought I had a urinary tract infection because I had those symptoms, so I went to the doctor and got tested for a UTI twice, but both tests showed negative. But around that time the symptoms subsided and I was able to live normally again. Ever since then, I would always make sure I peed and got it all out before and after I masturbated, and for a while I was fine. But then about a month ago (Jan 13th) I peed, but still felt like I had some in there, but decided to masturbate anyway. I started to, but I decided to stop (before I was hard) and try to get that last little bit of pee out. Well I did, and then decided not to masturbate. And ever since then I've had that urge come back. I put up with it for about a week and then it started to go away. But then about a week ago the urge can back after masturbating again (I had done it a few times during the week before that day with no problems). I don't know what I could've done, I hope I didn't damage anything. I would also get a minor urge after I would dedicate, I've had that since I had these problems the first time around.
Anyone know what I could've done? Its making me really miserable and to make things worse I don't have a way to get to a hospital or something, and won't for a few days. (I don't know what doctor I'd go to since I've turned 18 since I went to my last doctor and he was a pediatrician, and friend recommended I get checked out at a hospital).
