good god man..speaking as someone who trims excessively but won't let a razor near her hooha (i have a precariously placed mole, okay?!), i would say nair might be a bad idea. i dunno, i tried it on my legs once and it kinda burned, so it might be too strong for ballskin. just trim them, that should be good enough...
get a mach 3 and sensitive skin soap. after shampooing and conditioning the nut hair, lather up the soap and shave downward while pulling the skin taut. you'll have nuts that look like boiled chicken skin in no time.
all i can say about this is.. there is no way in HELL id put nair by my genitals and DONT recommend that anyone does. it says on the bottle not to do that for a reason. a good one.
ahahaha. no. but when i was getting ready for my c-section, the nurse prepping me was a lady that my husband used to lust after...pregnant wfe being shaved by hot nurse....evil.
