Masturbation is a normal activity. I have been married for five years with a healthy sex life. However, I still enjoy being in control. Even though I have sex with my wife several times a week I still masturbate almost daily.
Your penis will not get smaller and you will not become infertile. Your body produces about 1000 sperm every MINUTE! Be young and have fun!
However, the only time masturbation becomes a problem is when you neglect your life to masturbate. You make masturbation a priority of normal life. As long as you are not doing that then your good.
Hi:) to answer your questions, Can masturbation lead to smaller penis and "bad performance" when I do have sex? No it cannot lead to a smaller penis. Your penis size is what it is..Yes it can get in the way of you performance if you do it too much. As for infertility, NO excessive masturbation cannot make u infertile....Listen, you're young and masturbating is normal. If you feel you are doing it too much then try and keep yourself busy and focus on other things...But you are normal and you shouldn't worry about it!
