history: Once before it was a very hot day out and I had to drive to the store in my car with no A/C and I sweat so much that a had sweat stains on my butt and other embarrassing places. I live in a really hot climate and I'm a really sweaty person
current: That must be really hard to deal with.   have you tried an aluminum free deodorant?  It helps me 
next: That might help my arms, but one time I sweat so much on the way to the store that I had a big sweat stain on my butt!
