Thanks for your query.Based on the facts that you have posted it appears that you have
been indulged in masturbation
frequently.Masturbation is very common at the age of adolescence.
First of all there is myth in a mind of common man that excessive masturbation can lead to some problems in sexual activities in future. But I would like to state that it has been discussed in scientific forums all over the world and proved scienificaly that masturbation does not have any negative effect on any organ or system in the body.

and there by improve your sexual performance,
1) Practice moderate exercise for 45 minutes followed by meditation
for 1/2 hour.

A,C,E,D.fruits and vegetables .
3) Avoid alcohol and smoking
