you can tell him, but it's unlikely it will change for a long period of time. I was married to a guy who didn't like bathing, and I bribed him, threatened him, gave him ultimatums, and the best it ever got was when he bathed up to once a month. Now, we weren't sexually active, but I know a girl in your position who was sexually active with her man, and would only have sex with him if he bathed that day. Try that, and as for the sleeping thing, try flipping over the mattress when he isn't looking.
