This may sound a little weird but basically I noticed while masturbating when I rub the head of my dick I get the feeling I'm about to pee, and if I relax I'll just start peeing, doesn't matter if it's hard or soft. After I cum if I keep rubbing I'll start peeing too. It's a weird sensation too, not really pleasurable like ejaculating but kind of good in a way. Does anyone have the same thing?
Probably something to do with the stimulation of the prostate gland. Also, it's not uncommon to find it necessary to pee shortly after ejaculating, as this is Nature's way of rinsing out the pipes.
Different nerve endings have different sensations depending where the nerves are located. The peeing sensation is identical to what a woman feels when her G-spot is stimulate. Unfortunately for men, women have 50 times more sexual nerve endings than men. In my next life I want to be a woman.
i have noticed a similar thing myself when using a shower head to masturbate. i discovered that using the fast flowing water to stimulate my penis was quite exciting and that when it hit my penis in a certain spot (somewhere on the tip) it caused the symptoms you described. its never done it while i've just been rubbing though, only when using shower head. im sure its perfectly normal, maybe the nerves that cause this (in your penis) are just a little more sensitive then most guys?
