Some ideas to beat the heat... any  more??

Cool shower with a friend, let her  fix the "shrinkage"
Pyrex dildo ... chilled,  courtesy KaraXXX
Skinny dip  
Popsicles  use your imagination plus they taste good!
See a fine lady (you're going to sweat anyways might as well enjoy it!)
Lay naked with her afterwards under a ceiling fan (love that)
Ice cubes share them with someone you lust
Ride in a car with air conditioned seats, no panties (just for a special friend)

Have fun, stay  hydrated,  shop  early ,  shop  often
