Unfortunately polygraph tests aren't that accurate but I'd still love to see the results from something like this. There are similar fake polygraph tests done on the subject of bestiality but none of the ones I've seen are gender specific. I've got a few independent ideas lined up to test for these things one day, I wouldn't mind trying out the polygraph test thing out on my own sometime but not for a long while though.
Anyway, the original linked article is from 2003, they did an updated version of it back in 2013, it's worth reading as the women are now posting up higher averages than the men via the fake polygraph test.
Ever have that awkward talk with a romantic partner about your sexual history -- about how old you were when you lost your virginity and how many people you've had sex with?
