One of life's strange pleasures that I think is never mentioned is that wonderful near-orgasmic feeling of the first few gulps of cool water when you're really thirsty, like after a long walk or run or bike outside.
I had it a few days ago and it actually made me nostalgic for when I was 15 or 16 and would ride my bike 5 or 6 miles to play soccer and football with my buddies then ride home and get home so thirsty I could barely speak...I'd drop my bike in the yard and run in the house to get water.
I realized why I was getting nostalgic was because since I was 18 I've always been a bit more careful about having enough water....so getting that thirsty doesn't happen so much anymore.
Also, now most of the hot days have beer in them to quench that thirst.
But I mentioned this at work yesterday and the guy I was talking to looked at me funny. I guess because I referred to that wonderful feeling of the first few gulps as a "watergasm."
