I'm a guy, but I've a noticed a disturbing trend in advertising for female "all over" deodorant. One current ad even features a song with the lyrics, "My neck, my back..." Yes, I know it was already a song but suggesting that women's necks and backs smell bad seems a little over the top.
Personally I can't have anything to do with any of the aluminum based antiperspirants because they cause eye discomfort. I take frequent showers and got introduced to cologne by my evil twin.
