A body with ass, pussy and Boobies is attractive enough to fuck, that's what our instinct cares, you don't need to work hard or laugh much that makes a women look insane or stupid.. .. but to be honest it's a guys job to make her laugh ridiculously, until her stomach hurts and eye start shedding tears of laughter... So yeah!.. Don't blame yourself if you don't laugh much it mean a guy is failing at his job, nothing is wrong with you... ❤
I don't think there are many guys that PREFER a girl that rarely smiles. A girl's smile is one of the main things that will attract me to her. Also to some guys it might suggest that the girl may be hard work if she is unhappy all the time, which sounds bad but that can very well be the case. I don't think I know any girls that rarely smile though.
