Sexual fantasy has many important functions.
Firstly, it guides us to find sexual goals and provides a more visual picture and specific content for our general sexual impulses.
We have fantasies about certain types of men or women, and as we fantasize, we feel that their attractiveness becomes stronger and stronger. However, our fantasy objects may be illogical or unattainable, which is also one of the flaws of fantasy. We can imagine perfection, but it is difficult to find the perfect person in real life.
Secondly, sexual fantasy enables us to make adequate preparations for possible scenes.
Sexual fantasy is equivalent to a dress rehearsal. Let's rehearse different scenarios in our minds. This way, we can be prepared for what may happen during a date, after a party, or while in bed with our partner.
Third, sexual fantasy allows us to escape from the tedious or heavy reality.
Constant or mechanically repetitive work often triggers fantasies in order to get rid of boredom.
Fourthly, even if sexual life is highly satisfying, we may still indulge in fantasies and bring new ideas and excitement to our relationship.
Fantasy provides a safe outlet for curiosity in sexual instincts. Research has shown that some women can achieve orgasm solely through fantasy.
Fifth, sexual fantasy has the same expressive effect as dreams to some extent.
Sexual fantasy indicates our existing interests, happiness, anxiety, fears or obstacles. Because fantasy only contains a small part of the details in reality, the content we choose is very important - they convey our feelings hidden beneath the surface of consciousness.
For example, fantasies about extramarital affairs may indicate deep dissatisfaction with marriage, while fantasies about erectile dysfunction may convey fear of sex or concerns about a relationship with someone.
