I've always been self-conscious about the size of my penis and testicles. I'm on the small-to-average size, but always been able to sexually satisfy all of my lovers. One aspect of my sexual function that I've always been personally proud of has been the volume and force of my ejaculations. The amount of semen I would produce can only be described as "copious" and I could easily ejaculate over my head and onto my own face. Sadly, as we age our ejaculatory function becomes diminished, often dramatically so. After mourning the loss of my own ejaculatory prowess, I found a way to restore it to the way it functioned when I was a much, much younger man.
Here are the methods I have found successful in restoring my ejaculations to a more copious, forceful state.
Hydration.
I cannot stress this enough. You must be well hydrated in order to produce a healthy amount of semen. You should be drinking the recommended amount of water for your age, but the best rule of thumb is to dring enough until your urine is clear, and have to urinate frequently. There are numerous other benefits to being well hydrated, too.
Kegels.
Do them! Do a web search for instructions on how to do them and how often as the information is readily available on the net. You will see a noticeable increase in the force of your ejaculations in as little as a week, and even more as time goes by while continuing to practice them.
Expectorant.
