Ingrown hairs. I mean, they're awesome. My first encounter with this sect of magical hair was through the unpleasant experience of shaving my own bikini line. Some people totally are into that process of hair removal and that's cool -- I detest it. I'm usually rocking the fullest bush imaginable. Like I can twirl the hair. I'm v cute.
But -- when I do want to go smooth, I get a wax. And yes, my favorite part is getting a lil' butt crack hair removed while I'm at it.
The only positive aspect of shaving for me is the promise of ingrown hairs. Yes, they come up naturally from time to time too, but it's definitely more of a rarity. A vaginal unicorn if you will.
