i love beards on guys but full beard no gotee or mustash ...but it depends on the guy really, I love beards so munch I asked my boyfriend to grow one and it looked so bad on him..it just depends.and if your old its better if your clean shaven so you don't look creepy..here are some explames on guys it looks good on link wp.clicrbs.com.br/clubedabolinha/files/2012/02/03piqu%C3%A923022012.jpg linklink but my favorite is even stubble just make sure to keep it short and clean .go ahead you'll look awsome
I'd say a stubble is pretty attractive, as well as being neatly shaved. If you grow a long beard you'll start having food caught up in it, which is definitely not attractive. It all depends on your face and how you look with it though. My dad has been sporting a full-face beard his whole life and chicks were digging it (it isn't really long though, just about enough for a hair to curl one time). Don't go as big as the Epic Meal Time guy though, it's most likely not to end up looking good on a guy.
I am not a fan of full on beards like the ones that are long like Uncle Si of of Duck Dynasty, but I definitely LOVE facial hair... :) A goatee, or a beard that they just keep to their face, they don't let it get long (sorry I'm not sure what it is called). Haha :)
