data collected by international dating site Plentyoffish.com.
The site looked at 315,478 users frequenting no-strings-attached dating sites. Since 2004, the number of women seeking only an "intimate encounter" has risen from 9 to 18 percent. And while men seemed to outnumber women 10 to one in the quest for a casual tryst back then, today's ratio is only five to one.
Some might chalk up the change in females' approach to casual canoodling to those oh-so-sexually open "Sex and the City" gals. And of course, some women have more sex than others.
But the spike might actually be due to the increased number of sites on which to look for dating and sex. In addition to spots for the general public like CraigsList, there are now specialized sites based on everything from certain populations (such as Jdate.com, for Jews) to sexual appetites (Lavalife.com).
Sure there's the usual biological explanation for why humans sometimes try to shack up with everything in sight -- the innate drive to propagate the species. Nevertheless, women have still not "adapted" to doing it like a man. Research shows meaningless lovemaking makes many women depressed. So, before you fall into bed with the fella you just met, take inventory of this checklist.
Tell us: Do you think women often enjoy one-night stands?

Charlie Sheen Among other lowlights, Sheen 'accidentally' shot ex-fiancee Kelly Preston, spent thousands on madam Heidi Fleiss, and symbolically took a chainsaw to his wedding portrait with Denise Richards. Ew.

Ethan Hawke We were sad enough when this brainy babe's artsy-smartsy marriage to Uma Thurman ended. But to then shack up and have a baby with the nanny to his kids with the hot blonde? For shame!
