I know ivillage, bleurgh, but I've just come across this and found it intriguing.
The part that stood out for me was this:
80% of men surveyed said they were happy with their sex lives, whereas only 61% of women said the same thing.
And the perception of how happy your spouse is is even more striking - 79% of men thought their wives were happy with their sex lives, but only 55% of women thought their husbands were happy.
(Full survey is here although the format is horrible, and extra ick points for the 50sog question
but anyway.
Anyone else find this interesting?
