OK, ya got to work your way into it, heres how.
on any particular day/night, do something fun, just say, hey babe i got a surprise for ya, then whip out some whipped cream , and do the body "sundae" thing, then let a few dates go by, then do some other nutty thing, say "got another surprise" and do something out of the ordinary like a full body massage or something. then after a few dates more, bring in the shaving cream and razor, and say i got another treat for ya,,,,afterwards give her the best licking ever.
this way she will not get offended, and think your doning her a favor!
also, (maybe the girls in the forum can help in this area) to prevent irritation of the area and ingrowns later, use a luffa sponge.
