Sexual fantasy
Sexual fantasies occur in almost all societies around the world. They are rarely put into practice, mainly because of cultural, social, moral, and religious constraints. In some cases, even a discussion by a person of sexual fantasies is subject to social taboos and inhibitions. Some people find it convenient to act out fantasies through sexual roleplay. People watching porn sometimes find their fantasies validated. A fantasy may be a positive or negative experience, or even both. It may be in response to a past experience and can influence future sexual behavior
