Waaaay too sweaty during sex

[whitehorse]

I sweat like mad during sex. Not a few beads on the brow from a "good effort" I mean pouring out sweat like I ran a marathon. I feel fine, but I'm dripping all over her, not cool. I often need to have a quick shower before snuggling up after sex. If I have the A/C blowing and a fan on it's not so bad, but she'll shiver....
I'm not grossly out of shape or overweight. I don't sweat like this during "normal" activity.
This totally sucks, any ideas out there?
