 So, if your husband or wife wants to sleep with you, to do what married people do together, you cant say, No. But both of you can agree to wait for a while without sleeping together, so you can use the time to pray. Then, soon after that, you have to sleep together again. If you dont, Satan might trick you. He knows you cant control yourselves very well. If you go too long without sleeping together, then he will try to get one of you to sleep with somebody else.
