Men have every incentive to have sex to pass along their genetic material, Laumann says.
But genitally they showed about the same reaction to male-female, male-male, and female-female sex."Men are very rigid and specific about who they become aroused by, who they want to have sex with, who they fall in love with," says J. He is a Northwestern University sex researcher and co-author with Chivers on the study.Only about one-quarter of women say they think about it that frequently.As men and women age, each fantasize less, but men still fantasize about twice as often.That doesn't mean men don't seek intimacy, love, and connection in a relationship, just as women do. "Women want to talk first, connect first, then have sex," Perel explains. Sex is the language men use to express their tender loving vulnerable side," Perel says.
"It is their language of intimacy." Men, on average, take 4 minutes from the point of entry until ejaculation, according to Laumann.Men are more likely to seek sex even when it's frowned upon or even outlawed: What turns women on? Northwestern University researcher Meredith Chivers and colleagues showed erotic films to gay and straight men and women.They asked them about their level of sexual arousal, and also measured their actual level of arousal through devices attached to their genitals.They are likely to be more attuned to relationship quality because they want a partner who will stay around to help take care of the child.They're also more likely to choose a man with resources because of his greater ability to support a child.Women were also more likely than men to call themselves bisexual, and to report their sexual orientation as a matter of choice.
