i would not apply any type of deodorant spray down there, it will just provide a media for increased bacterial growth and in the case of axe's aerosol spray that contains a type of denatured alcohol could itrritate the sensitive tissues, the crotch area contains apocrine glands just like the armpit, both development and maintainance are mediated by androgens, and in general have thicker secretions that do not smell very good , especially when bacteria are present. do not wear synthetic fabric underware(nylon polyester etc..) you should wear cotton underware. Keep well hydrated...limit foods containing garlic or spices...do you have increased sweating(aka-swamp-ass) problem? They do have baby-wipe type products for that area if throughout the day you are not feeling so fresh( god...sounds like a maxi-pad commercial) lol.... as for the girl problem, before engaging in sexual practices you should clean the area to your desired level. hey women get freshened up before sex,,why cant guys? hope this helps...as well as keeping pubic and ass hair trimmed to a low level could help.
