In India when you visit the barber, after the haircut if a head massage is requested, the guy giving the massage fixes a small contraption shaped like a motor on the back of his hands which vibrates and with this switched on he gives the massage. The effect is really great. I have never seen it in other countries. I cannot help thinking that if this vibrator is used for a HJ the effects would be delicious. One cannot hope for such a thing in India but I wonder why non of the MPs in BKK has thought of this.
