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?
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)
get her drunk
Yes
Yes set a alarm and get up in the middle of the night to pee
pee on it
yes
No he doesn't
No
you need to go pee and you may pee in the bed
Usually you do this so you dont pee in the bed. Yet it can be more comfortable than holding it all night. You most likely would pee before you go to bed so that you dont wet the bed. Also it may be more comfortable for you than to hold it all night.
