I need to know some good ways to masterbate. I am 12 years old. I've started going through puberty. Also, i am a virgin, im a guy, and theres this big blue vein over the top of my penis not up to the head but about 3 centimeters. And also, my size is 4 inches is that normal??
You sound perfectly normal. Just experiment and find out what feels good for you. There are some web sites that show mastubation techniques, but it is more fun to find out for yourself what feels good. Happy experimenting. John. ;-)
