I'm not sure how to say this but when I ejaculate I barely feel any sensation at all. When I first discovered masturbation (about 12 years if age- I am now 17), my orgasms were amazingly strong but now, for some reason, I don't feel anything. I know this sounds completely stupid but I do not wish to go to the GP about this because I am petrified on what they might find. I have done some research into it myself but I have not found any use of the websites I have read. I would not say I am particularly healthy, in fact I am overweight- possible borderline obese. Would that play a role in it? I have also read that the more you masturbate the less sensation you get- is this true? I would really appreciate help and guidance.
