My opinion isn't going to be popular, but it never has been with the ladies. I think most guys don't care. All these standards that women get frustrated at guys for, weren't created by men. They were created by women or the execs telling women how they must be. I think a woman is pretty smokin' just wearing a hat and t-shirt. I don't care about make-up, expensive, fancy, name-brand clothes, etc. That's YOUR fashion that YOU like and are into. No one is putting that standard on you but yourself, so to then to get bitter or frustrated with a man with a beard isn't exactly fair to the guy.
And the guys who do put in time to look good and all of that are often considered metrosexuals like they aren't real men...which is a standard created by men for other men. So, we grow beards for the same reason why you shave, tweeze, and pluck. It takes time to grow these masterpieces and yes, you have to groom them. I got a nice men's beard grooming kit about four months ago or so and it has oils, conditioner, a comb, etc, to keep it looking nice.
Like I said, you're literally only the second woman I've seen who said they hate beards. But if my lady wanted mine gone, then it's gone haha. Not worth fighting over.
