By clean, i mean like don't pick your nose in public ,snort, fart,that stuff. people may not do that when with the girl they like but pre-warning!Also soft skin is a must for girls. Some girls may want to stroke your hair, if so- make your hair 'strokeable' like dandruff-NO. putting gel in your hair, dont over do it.
too much aftershave just CHOKES the girl!!! so be considerate.
