After doing masturbation I mostly feel that I get a great pain which started from my stomach mid to my penis. I didn't get this pain always before 2 years but in this time this pain mostly comes to me. Fist I thinks its due to over masturbation but now I am doing masturbation after 45 days and also got this pain. Now I feel that whenever I excited for doing masturbation for more than 1 hr then after doing I get this pain. Kindly tell me some suggestions. Thanks.
