hi doctor, i am a 27 yr old man, i have been masturbating since I was 14. I have completely stopped maturbation since the past 2 months, since the past couple of weeks, I have noticed that after i pass urine , i get a tingling sensation and a small amount of sperms are ejaculated. Plus I also noted that the sperms that are ejaculated have lumps in it. I went to my doctor who diagnosed me, and gave me a precription of Mankinds Mahacef oz tablets and mankinds nuforce 150 tablets. please advise what is causing this
