I am 25. i used to masturbate a lot . LIke 4-5 times wk. one day i felt like my penis is nt getting aroused. i got scared & did my study & came to know that masturbation is nt all gd for health & try quitting it. Now may b i do it very rarely. like once in a week. arousal problem is gone. but now wht happens is while urinating some thick liquid substance like semen also comes out. the tip of the penis burns. If i masturbate regularly it doesnt happen. Bt when i stop masturbation  it starts to happen once or twice in week. i didnt have sex with any girl yet. i am not feeling like telling it to any one around but its freaking me in. any one who knows about it please fill me in .
