Erotic waking fantasies commonly occur during daydreams, masturbation, or sexual encounters with a partner. A review of research about fantasy found that about 95% of men and women reported having experienced sexual fantasies. Comparing the con­tent of homosexuals’ and heterosexuals’ fantasies revealed more similarities than dif­ferences, leaving aside the sex of the imagined partner (Leitenberg & Henning, 1995). How strongly religious individuals are appears to impact frequency and variety of erotic

fantasies. Men and women who are less religious fantasize about sex more frequently than those who are more religious. Further, women who are agnostic or atheist have a much greater variety of fantasies than women with religious beliefs (Ahrold et al., 2011).
