If anyone was sleeping over I'd be washing the sheets the next day anyway.. it would be gross otherwise. So I don't really care what they did in it. Obviously so your best to clean up and be quiet but either way id ask them to strip the sheets in the A.M. and I'd wash it but I'm not about to go searching for wet spots.

When I’m getting ready to leave a house I stayed a few nights at, I remove and pile the bedding under the guise of helping take down (undress?) the bed, but really it’s to encourage the host to wash them.
