Fantasies can have benefits, such as increasing arousal more than other forms of sexual stimuli (such as an erotic story) and increasing sexual desire.[7][8] Individuals who disclose their sexual fantasies to their partners also have a higher sexual satisfaction. However, whether people are willing to open up to their partner generally depends on the content of such fantasies.[9] A more negative effect of sexual fantasy is that it has been linked with sexual crimes, and indeed sexual offenders often report that they have had fantasies related to their offense.[4] However, such fantasies are also common among those who have not been involved in such criminal acts[2] and non-offenders do not use their fantasies to guide their behaviour.[10] Therefore, fantasy alone cannot be used as a sign that someone will become an offender.[2]
