I did it just out of the blue the first time.... don't really know what made me inspired. I've never had a desire to go back... I'm not completely neurotic about it... I typically only shave about once a week... I find that going longer in between allows me to have a better shave... but maybe I'm just lazy. Occassionally I will get itchy, but typically it's an ingrown, but never painful. If it helps her at all... I'm brunette as well.
