Before the fall Adam probably dreamed about sex more often than Eve. No, just different. Men and women were created to be different and that's beautiful. Another difference between men and women is sexual desire and energy level. Women usually have one battery from which they draw all of their energy for work, care-taking, and sexual intimacy.
Men have a built in spare battery just for sex.
In general, we can be exhausted as a marathon runner and still have energy for love-making. We can be sick with the flu and still be thinking about sex. The reason for this has to do with the way the male and female brain is wired. In brief, a woman's sexual libido is strongly linked to the emotional part of her brain. A man's sexually interest is less tied to his emotions.
