Three to 13 minutes is kind of a large window, is it not.  Does it not kind of have something to do with the, uh, satisfaction level of the partners?  There have been times where there have been games to see who could "race to the finish line" which likely makes the men feel like the Harlem Globetrotters and the women like the Washington Generals, but typically there's a desire to try to make sure both passengers arrive in the train station.

 So to speak.

Foreplay would seem to have something to do with the ability of the conductor to punch the ticket.

 "That's the word from a survey of 34 sex therapists, all of whom are members of the Society for Sex Therapy and Research in the United States and Canada. While some fudged the answer by saying the optimal time depends on the couple, most agreed it was sometime between three to 13 minutes. Sexual intercourse that lasts just one to two minutes was deemed "too short" by the sex therapists. The Associated Press reports that this strikes at the very notion that endurance is the key to a great sex life."

Guys everywhere puff out their chests like Tim the Tool Man Taylor thinking they last way longer than three minutes, while women pine for more.

 Of course drunken frat boys still subscribe to the notion they haven't done the damsel justice unless they have raised blisters on the unwitting victim's labia.

"Lead study author Eric Corty, an associate professor of psychology at Penn State Erie, The Behrend College, told AP that the purpose of the research was to ease the minds of those who believe "more of something good is better, and if you really want to satisfy your partner, you should last forever." Previous research published in the Journal of Sexual Medicine concluded that the median time for sexual intercourse was 7.3 minutes. This was based on a four-week study of 1,500 couples in 2005 in which the women in the study were armed with stopwatches. "

 Just what every guy wants during intercourse, a partner with a stop watch.  Are you kidding me?  How many withered at the starting gate?  To hell with the stop watch, why didn't they just get the women to go, "One one thousand, two one thousand, three one thousand ..." and really fuck with their heads.

"Marianne Brandon, a clinical psychologist and director of Wellminds Wellbodies in Annapolis, Maryland, told AP that it's difficult for older men and young men to make sexual intercourse last much longer than 13 minutes."

 Well that was like scraping a needle across a phonograph record, with said reference likely indicating what part of the sentence startled me.  We know young guys have hair triggers.  We have no sympathy, given their recharge rate is likely less than 13 minutes, also, the bastards.  But what is up with geezers?  Could we have a little more insight into that, please?  I am turning 50 in less than two months.

 "There are so many myths in our culture of what other people are doing sexually," she told AP. "Most people's sex lives are not as exciting as other people think they are." The study findings were published in the Journal of Sexual Medicine."

Wait?  Porn videos are not accurate depictions?  People do not suspend from ceilings and screw for hours with IV saline drips?  You mean they do it with their eyes closed and the lights off in less time than a Buick Commercial on Jay Leno?

 Looks like we traded lack of inhibition for opposable thumbs with our primate ancestors.

Tough call in this context as to which one of us got the better of the deal.
