Brag! You look good either way!
I like hairy and smooth guys. Bearded and clean shaven. It's all good, no bias here. But! ...bears & beards are a trend now as much as mullets were in the 80's. Of course you're going to get more "keep the beard" votes. It's the trend of the moment after all.
As with all trends, take heed not to become a fashion victim.
Some of these victims look like they're trying too hard too look mature. Or manly. Which only enhances how they are neither mature... nor manly. You are very cute, young and you are not fat. Enhance what you have! Don't use a beard! ...but if you must, don't let it grow too much.
