Coleflowers, r u female? (males and females work different, so yes its different, check out the links given above), developed pc muscles allow us to last longer by making us able to control and impede ejaculation, and it also makes our orgasms more and more intense and strong, wich is all nice, but, the thing i described lasted for a couple of days, wich was very unusual from the common sexual release one feels after masturbation, the thing is that the time you spend is not important, but as openeyes as said, it seems that you must be multiorgasmic to achieve that, i still have to try it though, i didnt have time to do it today...yet
