no deodorant, no cologne. quit wearing deodorant around 5 years ago because it was just turning into a gnarly cake of goo in my armpit by 10am. once i quit wearing it my armpits quit sweating as bad and i havent put any on since.
never had girls complain, in fact my girlfriend and all the ones previous to her have all liked the smell. in case you missed science class, girls are attracted to their mans natural scent, so i guess that explains it.
