I find there is too much body heat under the covers to fall asleep when 2 people are entwined. I dont mind it in the summer when there are not as much covers. I like to sleep with one or 2 feet stickin outside the covers to help regulate my temperature.

In case of a wet spot, I am not sure the protocol. I bet one can find that answer at http://www.askmen.com/dating/dzimmer/
