Makes sense... the surveys show a moustache is the #1 turn-off for men about women. More so than flab, no figure, no boobs, etc. At least it's treatable.
I'd be very cautious too, if advising a woman close to me. "Man face" is real and seems to be unavoidable for women on gear for a long time. A slightly enlarged clit is a minor issue IMO, as is facial hair which can always be lasered or waxed, but some other things like an adam's apple, strong brow, strong chin, big nose, deep voice... all of that adds up to a change in gender which is completely unattractive IMO, but I'm 100% straight and I suppose others have different ideas of what a hot chick looks like. And that's cool. Diff strokes for diff folks.
I can't get into chicks who have manly shoulders and veins, among that other stuff. The achievement is impressive for sure but the androgenicity is a turn off for most men. Maybe the chicks doing it just don't care about losing appeal to those men, or don't mind the partial gender shift.
