do you like guys with full grown beards and moustaches? or maybe just one or the other. what's "sexy" to have? long, maybe short, maybe just the opposite and maybe just scruff. What do you think with one or the other?
Depends upon your facial features and facial structure--as well as your genetic ability to grow appealing facial hair.
So would you look good with it? I have no idea.
If you want to try, keep it well-trimmed and cared for. The only style that fits most all facial types is a goatee, so that might be a good "starter" style to try. If you can pull off the designer stubble look, that's also a good one to experiment with.
All other styles--including a full beard--really depend upon your individual characteristics as to whether or not it would look good.
Stubble works for me as well, I look much younger if clean shaven, which sounds cool, but it's not. Rather attract women around my own age. I still get carded with the clean shaven look for cigarettes:/
