Respected Sir, I am masturbating since age of 10 on &off basis (now 27yrs male) and length of my penis is 4 inches after erection &girth is also less. I feel some transparent lubricant (Not semen) is coming out from my penis with or without erection while taking to my girlfriend or doing something pertaining to sex. I asked to my married friend. He does not have this problem. Please advice is it normal or can cause any kind of problem and length &girth is normal or not.

Everything is normal with you. Transparent fluid is prostatic fluid which comes out on excitement in some males. It is also normal.Type word masturbation in search box of the site (on your right side top) and then click go. You will get all answers on masturbation.
