Is it normal to get this sweaty?

I believe it's something most guys have or will go through in their lives. My gf of 2+ years and I have a great sex life. Its adventurous, exhilarating, almost everything we could want out of it. Only one issue. I sweat alot. When terms like "drenched, dripping, soaked, etc," are flung around, you know there's a problem. It's sex. Not a 110 degree monsoon in a rainforest.

Let me spell out the facts.

I'm a 165lb, lean 5'11" in my early 20's.
I exercise only periodically.
My diet is mostly vegetables, pastas, and fruit.
My core temp runs warmer than most.
I perspire in situations most people couldn't.

And if it's not normal, what exercises, habits, routines, foods, etc. can be added to ones daily routine to
A. Lower overall core temp.
B. Increase heat tolerance.
C. Avoid perspiring so much during sex.
