Genes affect women’s ability to reach orgasm
Women who have difficulty reaching orgasm can blame it on their genes. Like heart disease, anxiety and depression, scientists discovered in a study of 1,397 pairs of female twins there is a genetic basis to female orgasm.
“We found that between 34 percent and 45 percent of the variation in ability to orgasm can be explained by underlying genetic variation,” said Tim Spector, of the Twin Research Unit at St. Thomas’ Hospital in London. “There is a biological underlying influence that can’t be attributed purely to upbringing, religion or race,” he added.
Other studies have attributed differences in the ability to achieve orgasm to cultural, religious and psychological factors.
Between 12 and 15 percent of women don’t have orgasms compared to about 2 percent of men. Males are also quicker, reaching orgasm in 2.5 minutes, while the average time it takes for a woman to reach orgasm is 12 minutes, according to Spector.
And there, in that last paragraph, in a nutshell, is the difference between men and woman!

Before giving Spector’s work a tacit thumbs-up, you might want to have a look at
1) Lisa Lloyd’s critique of Spector’s conclusions http://philbio.typepad.com/philosophy_of_biology/
2) John Hawks’ concerns about Lloyd’s critique and his subsequent acceptance of Lloyd’s critique http://johnhawks.net/weblog/reviews/evolution/dunn_female_orgasm_heritability_2005.html
and heck just for fun, my more general critique of twin studies, and Spector’s twin work in particular at http://www.sporula.com/blog/?p=19
Besides, everyone knows the real difference between men and women has to be with who needs mascara 
Hope this helps,
