The phenomenon of Cowper's gland secretion occurring upon whipping of the buttocks is not new. It was known as far back as Roman times and was observed when men were punished at the whipping post. There is a reference to this at the following location:
I have severe sexual dysfunction and cannot orgasm easily. To avoid "wet dreams" I have my wife spank my buttocks pretty hard with a paddle about once a week while I hold paper towels on my penis to absorb the inevitable release of Cowper's gland output. This avoids waking up in the night with soaked underwear. The output is NOT urine. It is a very slippery natural sexual lubricant and can be very abundant.
