I am uncircumcied, and my glans is not sensitive. I started to masturbate when I was 10 years old and now I m almost 14. Right now every time I masturbate I cannot really feel the orgasm(I know what it feels like, because I used to feel them but now I can t), is it because my glans are not sensitve, or because I use the same way to masturbate, or is it because I masturbate too fast, or is it because I masturbate too often(about 1 every 1-2 days, max. 1 per day), or is it because I started to masturbate too early??? What can I do to fix this problem??? Is this a type of health problem? I m really worried! Please Help Me!
