Masturbating to exhaustion.

I masturbate a lot, I like to do it and what I feel pushes me to do it as much as I can, for me any masturbation lasts over an hour, I have to take my time before I start masturbating because once I start I can't stop anymore. The pleasure of masturbating pushes me to masturbate for hours sometimes I feel exhausted my hands feel numb but I can't stop the pleasure is too much and after 3 or 4 hours of masturbation I want to do it more and more. I sometimes have whole nights of masturbation, I start in the evening and masturbate until it's light and it's still not enough. I know I spend hours and nights masturbating, but that's how I work, it's not enough no matter how much I masturbate. I finish after a long masturbating session and within 10 or 15 minutes I want it again and start masturbating for hours and still can't get enough. Masturbation is my pleasure.
