you dont use shaving creams and stuff on armpits. just hot running water.
this is pretty much true for legs as well. its all done in the shower with running water over you.
if your legs are full grown out then the first time you might need cream. but after that you just do a water shave touch up like every 3 days, and it takes all of like 10 seconds.
and it needs to be said to an inexperienced girl thinking about shaving.
YES you DO need to shave your coot. and keep it up as often as you shave legs and pits.
its not about "oh well no one is going to see it"
its dirty for chicks to have so much pubes
