Dating and courtship provide many examples of indirect communications. The young man may want sexual intercourse. The young woman may want marriage. In the initial stages of the dating game neither knows just what the other wants. Hence, they do not know precisely what game they are going to play. Moreover, in our culture direct communications about sexual interests and activities are still felt to be discouraged, even prohibited. Hinting and alluding thus become indispensable methods of communication.

Mosher et al (2005), from the NSFG for 2002, reported on the percentage of each age group who had experienced oral sex but not sexual intercourse.
