What couples should do is to communicate to each other why they want them to do certain things. Make it clear that you are not trying to control the other but want to protect the one you love. Do not take it for granted that he or she will know. Although this subject is taboo in many societies, sex is an important part of a relationship. You will be surprised to learn that many people still stick to old beliefs.
Many men are only concerned with satisfying themselves.
Many women are still under the belief that they should do what is necessary to fulfill their husband's desires and not want the same for themselves. It is fortunate to some degree that society is changing its views on this misconception. Couples should first understand that their bodies have certain needs. They need to satisfy these needs and realize that this is a part of their love life. There is nothing to be ashamed of.
