I don't think all men pee their bed in my experience. Actually, us women have been known to wet the bed as well. Probably as much if not more than men due to child birth, uti's etc. So why do you ask?
maybe because nervousness can cause that or scared during your sleep... i find this odd though.
it is liquid and everything you drunk
He was drunk.
maybe you can first try to pee in diapers first on the bed. Do this until you can always pee immediately and naturally when lying on the bed. Make it a habit and you will pee the bed when you take off the diapers. (think twice as it may not be easy to go back)
