For me it's about three. Usually something fairly mild, Bay Rum or Pinaud Lime Musk.
My wife has told me she doesn't want to smell anything but me when I get into bed. No enhancements needed.
Aftershave for me is only applied after my shave... The rest of the day i'm wearing one of my colognes and because of the nature of my job (inside an office) it lasts for the majority of the day. !
