Is it normal for a girl to grow hair around her butthole

I think it's normal. My ass is so hairy and I'm a girl. Why bother to shave down there... it's hair, it's harmless. I can't even spread my ass wide enough to get the hair down there without cutting myself anyways. Trust me, a cut right on your ass where you sit is NOT comfortable.

Normal.

What is freaky about having natural hair around butthole? I, guy, myself shave my body like Spartan but wouldn't bash no girl for keeping body hair around private areas.
Legs, arms and buttcheeks on the other hand is a must-shave/wax for girls.

You mean like in a hanging window box?

It's not something that usually happens, so by definition it's abnormal. It's still her choice to shave/wax it though.
