I am 20, and i am having this problem from past 5-6 years. Earlier it only used to be after masturbation things thats why didn't complaint about it for long to anyone but from past 1 year it has become very chronic and severe and happens even when i don't masturbate. i have been taking continues medicines from last 10 months and have seen 3 doctors. Initially i was given treatment for prostatitis for 2 months which seemed to work but the problem again recurred after 1 month after that i was again given the same treatment but it didn't work and now from past 2 months my doctor is treating me for bladder pain syndrome as the doctor says my nerves are causing irritation but it is also not effective. Though it has reduced the severity and the time period for which i have burning sensation now. All my tests have been negative i have even got my cystoscopy done but it came normal. Didn't had sex yet. Now i even get burning sensation from mere erection and burning does not happen during erection but follows after 30-40 mins. If someone can tell me about it anything helpful please so it. It has troubles my college life.
