Hi everyone! This is the first time i try to tell anyone about this. The reason I am is because I can't seem to find a cause for this problem, or how to stop it.

Basically I've been losing sensitivity gradually ever since I began masturbating.
I suppose this might be personal details, but when I was 12, I could reach orgasm atleast 6 times in one day, every other day. I was pretty much addicted to masturbating back then. When I came, while sitting down on the toilet, I would usually just miss the ceiling, and I have hit it a few times!

Obviously I don't masturbate that much anymore, that only lasted for a short while. But I have always done it at least once a day. When I got my first girlfriend a few years after that, we would have sex many times a day, and I could come several times before having to stop. However, during our 11 month relationship, I felt i lost this ability. I didn't notice it too much since it is pretty natural for people's sex lives to kinda wear off a little over the months, especially when it has been that active.

To get to the point, I am now 17 years old, and I feel I have completely lost the ability to have sex. I ejaculate very little, which doesn't come out with all that much power, and the minute I put on a rubber I'll be soft 2 minutes after (I have tried many different brands and sizes).
I cannot masturbate once a day anymore. If I masturbate, I'll loose my sex drive for at least 2 days, where nothing at all can turn me on and I'll feel no attraction what so ever to woman (unlike the old days where I would sometimes have to masturbate in school just to be able to concentrate in class). If i try to masturbate anyway, I'll have to work very hard to even get erect.

When having sex, I'll usually not reach orgasm at all. I need at least a few good porn sites in order to get turned on enough, and the women I've been with haven't been able to turn me on enough, despite being open and experimental with our sex life.

Obviously it was too much when i was younger, and how horny i was got in the way of my everyday life. But I really feel like I've lost my sexual power, and I miss it! What can I do to get it back ?? What ever went wrong?

I am not circumsized, take no meds, live a generally healthy life with lots of sport, healthy eating and I'm a happy person.

Any suggestions or comments on this will be greatly, greatly appreciated!! I really just want to know if this is normal or if I have some rare deficiency deseise or something.
