sorry for taking so long

Masturbation is normal, healthy, and fun, and even necessary for male sexual health.  Most males your age masturbate daily.  Sometimes a masturbation session last two minutes and sometimes 15, so I don't think you have a problem.  Sometimes your mind is in just the right place to make you orgasm and other times it takes prodding.  An average of 5-10 minutes is typical at your age.  

Your technique is the standard one.  For best results in sex, use as little pressure as is necessary to have an orgasm.  Your penis will adapt to intercourse nicely.

I write from the point of view that masturbation is normal, healthy, and fun, and even necessary to sexual health. I am able to answer questions in all areas of sexuality.


I am the author of the web site and have been answering questions about sexuality (especially masturbation) from both males and females for over 13 years.

I have a Ph.D. in a field unrelated to sexuality from one of the leading educational institutions in the world.
