It’s not birth control pills (usually), it’s age and heredity.
Having noticed over the past 40+ years that women in my family are rather hirsute at the best of times, and post-menopause are just effing hairy, I have long known that I would be growing a goatee at some point in my life.
As it happens, I have vampire-pale skin and dark brown body hair. Lots of it. And my skin is sensitive on top of everything else, prone to rashes and what not.
So I shave. I don’t wax, don’t use chemicals. Shaving is the least irritating means for me to mow the lawn and trim the hedges. I do the legs in summer but in winter let the forest grow. My husband accepts this as a fair compromise, as he finds rashy, oozy, weeping, sore encrusted shins even more distasteful than a wife with a thicker pelt than he has (I’m half Russian. He has a siginificant dose of Native American. I’m not kidding when I say parts of my body are much hairier than corresponding parts on him).
Yes, I shave the damn chin and upper lip. I’m told that it is somehow horrible and unfemine to do so, but the scraggily shit that grows there is damn unfemine too. If it grew thick enough to be called an honest beard I might quit the office job and join a sideshow but really it’s just crap to look at, it’s bristly, and I choose of my own free will to make it gone. I expect this stuff will only get thicker and more abundant post-menopause. What I do then I haven’t a clue.
And, uh, oh yeah - I have a unibrow, too. Have since childhood. Despite hearing much about how horrible they are I have never found it a social obstacle, and I’ve never bothered to pluck, trim, or otherwise restrain my lush eyebrow growth. I just never saw a need to do so. No doubt someone out there considers me a barbarian for not doing so, but then they would probably be aghast I don’t shave my pubes, either (when did that get to be the fashion?) I’ve also been known to wear black shoes with brown pants, which I’m also told is a no-no.
I’m just fashion and style impaired I guess. And fuzzy.
