Grinding

Grinding can be done where the individuals are facing one another or in a spooning position where one partner's front is pressed against the back of the other. It can be done during foreplay or by those who abstain from sexual intercourse, but are not opposed to heavy petting activities. Generally, when using the term grinding, the act is performed while clothes are still on. In some cases, it is used to describe the deep grinding movement of the hips when a female is the top partner during sexual intercourse. In this case, the term can be thought of as a synonym of riding.
