I shave my armpits every time I take a shower (which sometimes isn't as often as it should be - my grooming habits can be awful).
As for legs, I have a lot of trouble shaving them, although I try my best. I can usually only half-shave them if I don't want to hurt myself, because I'm very clumsy. Cutting myself is annoying not so much because of the pain but because of the bleeding, and bandages are uglier than leg hair, IMO. I don't shave my legs in the winter, either, only when I wear shorts/skirts in the summer or before going swimming. I don't shave my legs often because of the problems listed above and because of time constraints; it usually happens about every two weeks in the summer.
I use shaving cream for both the armpits and the legs. I used to wax my legs, but it was very time-consuming.
