I shave my armpits the same way most of the others do. I prop my left, BPI, elbow up on top of my make-up mirror, because it's the right height for me as it sits there, on top of my bathroom vanity. I use my non-BPI right hand to shave my left armpit. The right, non-BPI armpit is more difficult, because, like the others who have posted, my BPI hand can barely reach the other armpit. Also, my BPI hand doesn't have the strength or agility to do the job. Therefore, I use the monkey position that the others have described, and shave my non-BPI armpit with my non-BPI hand.
Sometimes my husband will do the shaving, but I know that he doesn't like doing my personal grooming for me. He barely likes doing his own!
