I've heard it gets easier, the more you do it. I've never done it myself, though.

As for hair growing back in a way you don't want it to, it sounds like what happened when I shaved and had a tuft of hair growing back at the top (where the outer lips meet), like a tight, little bunch of hair that wasn't soft and loose, like the hair normally is. But I kept shaving (because I hated that tuft), and eventually, it started growing back normally, and I haven't shaved since. Still, it was easier to clean, so I did like that.
