Sexual fantasies are sexual-themed mental representations. They can be produced voluntarily or involuntarily by our mind and are quite common, although most people keep them for their privacy.
They usually appear at puberty and accompany the human being for the rest of his life. It has been proven that both men and women fantasize with the same frequency but their fantasies are different and men tend to explain them with less modesty than women. Fantasies do not depend on age or sex.
Having fantasies is something completely natural and healthy from the psychic point of view since they serve to disconnect the mind from everyday problems, it is an escape route that leads us to evasion. In addition, they have an aphrodisiac power that can increase sexual desire and arousal. In fact, it seems that having few or no fantasies could be an indicator of Hypoactive Sexual Desire or suffering from a picture of stress.
For this type of fantasy to be considered as something pathological, they should affect the life of the individual and be their only way of having sexual pleasure. In this case we would speak of paraphilias, in which the fantasy becomes an obsessive act, the end of which is not sexual gratification but rather to carry out the situation generated by the person's obsession..
Sexual fantasies help to improve one's pleasure, since they stimulate the libido, so it is healthy to have fantasies and we should not feel guilty about having them.
Two types of fantasies can be defined, the so-called "creative" that aim to enrich the sexual relationship and awaken desire and the "longed for", these refer to what you would like to happen. Almost all, both of one type and the other, report pleasant sensations, although sometimes there are people who may have fantasies that are disturbing to them, such as dreaming of a rape, if the fantasy is recurrent and causes discomfort to the person, it should be investigated the origin since there could be some trauma or unconscious fear in the person.
It depends on the type of fantasy. According to specialists, some fantasies are better to remain in the imagination and to carry them out could compromise the physical integrity of the participants and are classified as crimes, for example, having sex in public. Other fantasies can be put into practice as they can help stimulate sexual life and overcome some inhibitions..
The best thing is that it is the same person who decides if it is better for them to stay in the world of fantasy or want to try it in real life. But if the person is in a sexual relationship in which his sexual tastes are in line with those of his partner, there is no reason not to share the most intimate fantasies. Anyway, you always have to assess whether the fantasy can bother the other. In a relationship, not everything has to be shared.
