i was speaking very broadly and in extreme general terms without going into details. And if there are other possibilities that rule out a bed be creative and find somewhere that is usable, the floor was an interesting suggestion, etc
Now that is something proper to worry about. It is rather embarresing to happen, although one can always warn ur partner of what may happen and so they are prepared for it, or u could just not drink as much which is way less fun
Why would you need more room? Generally you are laying on someone or there laying on you, thus meaning that half the bed is not being used and u may as well have just used ur own bed.
