Well I wouldn't say it was painless...
Make sure you get a good waxer, pref one that uses hot wax instead of strip wax, much less painful.
Grows back a lot finer than shaving, no prickles.
Let's just say it will be considerably less painful than giving birth
it was the second most painful experience i've had (second to childbirth). i was sweating so bad from the pain i soaked through my clothes. I have a high pain tolerance, too. NEVER AGAIN! i bought a laser hair removal thing and need to start using it NOW so i don't have to worry when i get too big!
