I know that before a contest it's good to dehydrate yourself to bring out the cuts and tighten the skin and all that.
But how do you do it exactly? How do you know when you've done it just right, too much, or not enough?
The other day I spent almost 2 hours in the sauna and didn't drink much water. When I came out I had massive cock veins all over my body. But I think I could have gone further with it.
Can somebody school me on this? What's the protocol usually?
