Almost everybody who doesn't have naturally well kempt brows here get theirs done. It's not considered femme, it's just considered good grooming.
I have mine threaded and it's a much nicer process than plucking or waxing. Not painful, doesn't leave you all red, and gives a much more natural look.
I remember when I was in the Army and stationed in Tennessee. The first time I walked into a salon to ask if they did eyebrows the response the woman gave me was "but yore a mayunn?". Apparently having them done is just about unheard of up there (or at least was 10 years ago). Needless to say I walked out looking like a surprised drag queen.
Lesson learned -- make sure the person doing your eyebrows is either a guy or is very experienced doing guy's eyebrows.
