Hi please excuse my bad English, i m 23 years old and i haven t had sexual intercourses before.. I used to masturbate very frequently till i got 21 but now it s almost once or twice a week, problem is after urinating i feel like some fluid needs to get out and i push it till it gets out and i keep pushing till i feel it s all out, it s like a sticky yellow (or light green) substance that looks like a substance i usually get after ejaculation.. some times it even sticks at the toilet containing small brown stains by time, some times i sense really bad stomach pain and i have to go to the bathroom and get this sticky fluid out and then i feel relieved , is this dangerous? , thanks in advance.
