personally, i pretty much always find whatever facial hair on a guy more attractive than clean-shaven, as long as it's not out of control and is somewhat taken care of. it just makes a guy seem more masculine to me, which is what i personally prefer. but i know i also hold the unpopular opinion of finding moustaches kind of endearing, rather than creepy. i like dad vibes i guess, and they give those.
but of course guys should do whatever they personally prefer and like for themselves most, cause confidence looks and feels best for sure.
