My DH chooses not to sleep in the bed, though admittedly it's much more comfy if he doesn't. I get more sleep co sleeping and so does DH which results in a happier mummy, and there fore a happier everyone! DH sleeps on a mattress on the floor in our room, or in DD's room on her big bed (she's still in her cot) or sometimes on the lounge. As for sex, we just find alternatives. It doesn't have to happen in bed all the time. It rarely does for us if ever now!!
