I am 17yr old , male. Previously diagnosed and treated for prostatitis about 6 months ago. I am currently having burning sensation while urination. I get the sensation of burning in the urethra , inside the glans region. I used to masturbate rigourously , like 4 times a day. Now i have reduced masturbation to maybe 0-1 time a day. The burn is more when i urinate after masturbation. Urge to pass urine increases after masturbation because of the burning sensation. I am also passing stools frequently than usual with stomach ache , may it be because of that? Thank you. Please do advice.
