Please sit down with your son and explain to him about women's bodies. The world doesn't need any more men who believe that pornstars and Hollywood actresses are how women are supposed to be. He probably doesn't mean any harm with his comment, but that attitude is still horribly damaging to women who already are unhappy with their bodies.

I think boys should shave aswell....

A few females in my family actually don't grow armpit hair at all. They do however have hormone deficiencies...

Girls do more than you think

As someone of the same age, I've known women have hairy armpits since birth. Source: I'm Italian

Although I've always known that women grow armpit hair, I can kinda see his logic. Women don't grow facial hair (unless they have a hormone imbalance), so similarly,if he had never seen a woman with unshaven armpits, I can see why he might have thought women don't grow armpit hair.

The media is to blame? Aside from ignorant people that don't know about female anatomy. Women gave done this to themselves. Why women put on make-up? Why do they wear high heels?

Your son is an idiot. Tell him to step away from Xtube and start interacting with living, breathing, women.

you'd think being from Canada, with the very large French population, he might have seen a hairy woman

Hence the point of shaving them...your son will learn anatomy later...he'll then know...
