clean cut, or just a little stubbly, but only on some guys.

facial hair that looks clean cut

I don't particularly like it on younger guys (as in late teens). I'd prefer someone who is clean shaven, I think it is more attractive. As someone gets older, starting in 30s maybe, then I think stubble or a thing beard is really nice.

It entirely depends on the person; some guys can look good with scruff, while others require a clean-shaven look. I don't like a huge beard, however. That's too much.
