Thanks everyone. My situation right now is... complicated (isn't everyone's, to some degree?). He and I have this dynamic that has always transcended whatever else we have in our lives: jobs, stress, people, even ourselves. It's kind of weird, but really cool. It's a little bit hard though. If we spend too much time together in a non-public place, we frequently end up having sex, and that isn't necessarily the best thing to do depending on the circumstances of our lives.
The ice/water thing totally blew my mind, especially coming from him. I've played with ice before, inserting cubes it into holes and even freezing glass toys, but this was a completely different (and wonderful!) sensation. We had to move back to the bed after he emptied the glass on my back because I could barely stand...
