Never measured, but I can shoot quite a distance. Probably 6-8 feet, though that's a total guess. My cum has overshot my girlfriend on to the wall once following rear entry, so at least 4-5 feet for sure. I squeeze on my PC muscles, then just let go, and following that, squeeze right below the glans to constrict the cross section. Hence it travels further and harder. Much like what would happen if you squeeze a pipe to shorten the area of flow at the point of exit. Less area = more pressure for the fluid.
