I find the "Hitler Tache" or the "exclamation mark" more ridiculous than a bald fanjo if truth be told. Surely you might as well be bald!
I have a fairly normal triangle that I just tidy up with a wax - I wear my bikini bottoms to the Beautician and hold to one side for a bit of movement leverage. I have had everything taken off, it wasn't painful, there were nice sensations during sex, and it's definitely more pleasant oral for your OH. For me (pretty sparse, electric wire hair) I could go about 6-8 weeks between. However ingrowing hairs were something that I disliked intensely - having straight hair down there can't help this matter much!
However one of my friends had a real bikini line issue - and was taunted by one not very helpful male friend, that she looked like she'd spilt a packet of "Old Holburn" in her lap. She had to have regular waxing, arms, legs, eyebrows, upper lip, fanny - so for ease she just used to take the lot off. For her she was a regular 4 weekly person. I think she is considering laser hair removal now too.
She was paranoid about it, but I've met men that like a big fluffy muffty too, and sometimes my husband asks me to grow it back. So I hardly think it's all mens preference. There is a section of adult magazines that focuses on the more "hirsute" woman after all.
