My wife and I have no-hair policy. She is lasered smooth and me shaved/waxed smooth. Sex is much better without hair. Had to shave for the vasectomy and have kept it smooth since.
The hair on the mons pubis and labia have nerve endings right? Would stumulation of a full bush not facilitate sexual arousal?
Without the hair the skin is far more sensitive and foreplay is far more intense without the hair.
However if you shave too far down and ride your bicycle, not a good idea. The hair actually acts as a 'lubricant '. Without the hair, rashed skin...
