My husband of 20+ years has suddenly started paying much more attention to his appearance and also letting his stubble grow/ growing a beard. A friend joked that he’s trying to impress someone as men grow facial hair when they want to appear more masculine. Now I’m worried he’s tempted by one of his lovely young work colleagues as he has started spending more time with them in a new role. He has no history of unfaithfulness. Is growing facial hair really a ‘thing’ when men want to appear attractive?! Should I be worried?
