If a husband asks wife to keep Pubic hair for making him enjoyable during sexual relations?

Then the wife gets to make a choice to do it or not. The choice between 'bald is beautiful' and 'natural is nifty' is entirely personal; and happily, what is fuzzy on Monday can be smooth on Tuesday. In other words it's a change you can make (smooth to fuzzy, fuzzy to smooth) over and over. Try it both ways, and decide what you both like.
