Masterbate away my friend. Welcome to the coming of puberty. You'll realize that sometimes masterbating feels good and is actually healthy. Just don't go free willing too many times in a day yo' kno'. Cuz' than you'll find it hard to walk the next day, heh.
There was a recent news report that men who masturbate frequently have reduced instance of problems with their prostate glands. This was the result of medical research. Basically you're keeping the plumbing working the way it is supposed to instead of letting it decay in atrophy, which only makes sense. You exercise your biceps you will have big guns, you exercise your penis...
There is also evidence that keeping the pipe well-oiled can lead to a gradual increase in fullness over time, which can only please your partner better. :-)
Funny, but I had the same questions about frequent masturbation. Well now I am married, and whithout birth control for 1 month after marriage of 3.5 years we conceived right away. BANG a baby on the way.
My suggestion is that you take care of your *****. And never take it for granted. God gave you it for a purpose. To bare children. Make sure you are ready to care for and be reponsible for a child before you shoot it off.
