I thought that Beenie would pull the diaper off but she didn't.
She has now been spayed so we don't have that issue anymore.
As for sleeping in the bed, it's still possible.
Just put a towel in between you and hubby and put her diaper on anyway. She may get out of it but the towel will protect the bed from unwanted stains. :P
I wouldn't keep her ouside though... Probably be better for her to be closed in the bathroom with her bed until you get diapers and put a thick towel on her bed. Male dogs can get pretty aggressive when they want a female. You or her could get bitten in a confrontation.
