New York, April 23 (IANS): Men won't like this. Women won't enjoy this. But the truth is out. An astonishing 45 percent of men finish sex too quickly - in flat two minutes!

"Two minutes is way too speedy for the average woman to be able to have an orgasm through vaginal penetration alone," famous author Harry Fisch was quoted as saying on nerve.com.

Fisch has just released his new book titled "The New Naked: The Ultimate Sex Education for Grown-Ups" that is loaded with such information.

According to Fisch, the average duration is 7.3 minutes-only four minutes less than women's "ideal time".

The report supports the earlier theory of sex researcher Alfred Kinsey, whose research in the 1940s and 1950s concluded that three-quarters of men usually ejaculated within two minutes.

In an earlier paper published in Journal of Sexual Medicine, Czech psychologists Petr Weiss and Stuart Brody found that women’s chance of having an orgasm was much more highly correlated with duration of sex than of foreplay, the report added.
