Errmm.. okay. I have issues with masturbating. I ve been masturbating since 5 years running and I can t seem to get a grip of stopping or reducing it. I do it every other day and in a day I masturbate at most thrice. I have noticed when I wabt to urinate my penis doesn t stand erect like the response it should have when the bladder is full. It s almost as if I can t feel myself urinate. Another thing I ve noticed is that my penis seem to shrink after masturbating. It looks smaller compared to when 2 years ago or even last year and the scrotal sac looks dead. I hear cases of prostate cancer and I m scared. Pls help me

### output:

Degree understand your concerns went through your details. Masturbation is a natural habit and is not at all unhealthy if used in moderation. Thrice daily is definitely more than high level. Thrice or four times a week is ideal. Excess masturbation can cause loss of energy (which you can regain after taking one-hour rest) and may cause anxiety if you do not have proper knowledge about it. Erection while urination and while sexual urge are two different concepts and I suggest you not to confuse between them. Penis naturally shrinks after masturbation, but it cannot shrink in size. You are just feeling it because of low energy and tiredness. You should consult a urologist to have a confirmation and thereby peace of mind.
