My late husband had both a beard & moustache and I loved that about him & he kept them trimmed really nice. Now our son will do the moustache now & then.
I won't let my DH grow one. I have sensitive skin. I get a lot of whisker burns. Other than that they do help the look of some men and others they don't.
Hubby has a nice trimmed up mustache and he looks quite handsome with it I think. I have NEVER seen him without it...and that's fine by me. I am not a fan of full beards.
