1. Fantasies About Your Current Partner
No kidding. This is the number one sex fantasy for most men: things you've done, or would like to do, to your partner. (It's her top fantasy too, by the way.) Why? Because available flesh-and-*lo** is often more of a turn-on than the unattainable.

2. Having Sex with a Woman Other Than Your Partner
Often, she's a past lover, a friend of your partner, perhaps a celebrity. The psychology behind this one isn't too difficult: lots of people long to have sex with someone new and fantasy is a great way of indulging this longing without losing your partner in the process.

3. Giving or Receiving Oral Sex
This is near the top of the list for both sexes. Fantasy fellatio has one vital ingredient: the woman doesn't do it to give pleasure. She does it to get pleasure.

Fantasies about giving her oral sex are common as well. Many women are more obviously turned-on by oral sex than intercourse and you, as the ultimate pleasure-giver, want to drive her crazy.

4. Sex with Two or More Women
If having sex with one woman feels good, having sex with two must double the fun. Throw in some lesbian lovemaking and this one sends most of you drifting off into la-la land. In your fantasy, you're superstud: capable of bringing both women intense multiple orgasms. However, studies show the vast majority of men don't want (and actually couldn't cope with) such sexual demands in real life.

5. Voyeurism and Exhibitionism
Few people would be able to keep themselves from watching a couple having sex if they were guaranteed not to get caught. The reason that voyeurism is a popular fantasy for both men and women is that sex is private and mostly hidden. Sure, we've seen couples do it on video, but it's rare we get to see the real thing.

Exhibitionistic fantasies often revolve around others admiring you. You put on a fine show (of course) and the voyeur is usually envious of your sexual skills, desperately wishing they were the person you were making love to. It's an ego-boosting fantasy.

6. Having Your Partner Masturbate for You
Watching your partner "play with herself" is up there on most men's wish lists, possibly because it reassures them that women are as into sex as they are. Also, the related fantasy of spying on her while she masturbates appeals to your curious side: what is she really up to when you're not around?

7. Anal Sex
It doesn't mean you've got "gay tendencies." The anus is undeniably an erotic zone, especially for men. A lot of you would love to have her penetrate you with a finger--or want to have anal intercourse with her--but worry she'll think you're gay if you suggest it. So you fantasize instead.

8. Bondage and S & M
Being tied up is often a favorite female role, tying someone up is often a favorite male role--which works out rather nicely if you play this one out in real life! Bondage fantasies are usually about power--having it or relinquishing it, and both sides have their appeal. Bondage usually comes to mind because it's the subject of many scenes in erotic books and movies.

Sadomasochistic (S and M) fantasies are less common but certainly not rare. Sadism is getting off on inflicting pain on someone else; masochism is getting off on someone hurting you. Most mild S and M fantasies revolve around whipping and spanking. Pleasure and pain are inextricably linked in the minds of some people and, in reality, spanking increases *lo** flow to the genital area (and therefore turns us on biologically). Masochistic fantasies sometimes stem from subconsciously thinking sex is bad and that you need to be punished for liking it.

9. Sexual Ravaging
Contrary to what most women believe, when you fantasize about forcing a woman to have sex with you it's more about overpowering her through your amazing sexual technique and charisma than violence. She starts off saying "no" then can't help but say "yes," given the superhunk that you are.

Conversely, if she's forcing you to have sex, you're indulging in a submissive sexual role quite unlike the one you probably have in real life.
