My review is on the ManGasm.com "Prostate Stiumlators". In particular, the Mangasm Spark.....
I know. It looks a little complicated and you are likeWTF but these prostate stimulators are smooth and flexible They are curved to stimulate the perineum (the outer surface of the prostate that is very sensitive and can crive men to orgasm). It is made form a non-porous material and is safe to use with water-based lubricants. You receive maximum stimulation from the nodules that really vibrate along the motor. It has seven speeds of pleasure.
I had a guy friend test it out..and well......the approved! *thumbs up*
ManGasm.com are excellent resources for male products and are definitely SATSB approved :)
