Far too late in life, I began experimenting with my cock and trying to find new ways to pleasure myself. I've tried anal play, cock bondage, cock rings, sounding, e-stim, and various other things. All have provided some interesting differences but none really changed my ejaculation.
I began experimenting with prostate play, first trying to stimulate my prostate internally but also massaging it externally by pressing on my taint. I've never used an aneros or prostate toy (which I intend to do) but when I get the pressure on my taint just right, the feeling is wonderful and my prostate reacts wildly.
I'll put on leg on a chair or stool so that my taint is fully exposed. I massage and press on my taint until I find just the right spot. I use my other hand to more-or-less just wave or shake my cock back-and-forth without stroking. When I get things just right, I can feel my prostate get "happy" and the precum oozes up through my urethra and starts spurting from my cock. Sometimes, as much as a tablespoon which for me is a lot. I've made big messes all over the tile floor of my bathroom many times. At other times, I'll stop waving my cock and continue massaging my taint. I'll just let the precum pool into the palm of my hand. Completely clear and slippery as hell. I can rest for a minute or two and do the whole thing over again with very similar results in terms of the amount of precum. The feeling is amazing.
I've been able to "perform" as many as 3 times in rapid succession. When I feel that I've milked most of the prostate fluid, I'll sometimes wank to orgasm which then is the same milky white cum I've produced my entire life.
