I am fortunate in that I hardly have any hair under my arms to shave etc.. I know deodorants work better on bare skin than on hairy pits. My partner is European and only shaves her pits occasionally , much to the dismay of some people.... to each his/her own whatever makes you comfortable.
Recently I was able to take an extended leave of absence and the first day I shaved my body completely smooth from the nose to toes. Enjoying the exhibitionist lifestyle and never wearing anything except my nipple rings, navel piercings and frenum piercing that I occasionally have to feel swaying between my legs. Having my underarms shaved completely smooth was one of the most incredible and erotic feel and look. Not sure what others might think when seeing my smooth legs and body completely smooth...not having any problems, issues or concerns about what others seeing or caring about being naked or not shy about what I have always wanted and being naked and enjoying the natural look and natural lifestyle. Having gone naked for over two weeks and only wearing a t shirt and khaki shorts when going to the grocery store.
