This post is based on the article "Sexual Fantasy" that was published in Psychological Bulletin, Volume 117(3) May 1995 p 469–496 and is written by Harold Leitenberg and Kris Henning.
I have read it few years back, and thought you may find it interesting. I would love to hear your thoughts on this...
Leitenberg and Henning claim that there appear to be some notable differences in the content of sexual fantasies of men and women.
Men's fantasies are more active and focus more on the woman's body and on what he wants to do to it, whereas women's fantasies are more passive and focus more on men's interest in their bodies.
Men's sexual fantasies also focus more on explicit sexual acts, nude bodies, and physical gratification, whereas women use more emotional context and romance in their sexual fantasies. Men are more likely to fantasize about multiple partners and group sex than are women.
Finally, women are more likely to have submission fantasies, whereas men are more likely to have dominance fantasies, although both types of force fantasies may indirectly be serving the same purpose: affirming sexual power and irresistibility.
