How can one increase ejaculation frequency ie number in a single intromission time from the first ejaculation to the last time meaning duration of male sensations of pleasure?

For us males it is pretty much of a one time shot, then we need to build-up the semen once more,before the next ejaculation. We produce about 1 teaspoon of semen for the average ejaculation. The volume of the ejaculate is reduced if the time between ejaculations has not been sufficient to replenish the seminal fluid. It certainly is possible to ejaculate several times per day, but the volume of succesive loads will be reduced. Base upon my personal experience, in order to produce full volume the body requires about 48 hours between ejaculations.
