Also unsurprisingly, the age group of women most likely to want sex on the first date goes to those aged 18 to 24 with 14 per cent, the poll shows. In a sign of changing times, only 5 per cent of participants would hold out for marriage before having sex.
"Men have always been happy to jump into bed with any woman that shows the slightest interest and see it as a conquest, while women were often more served," says relationship expert Hillie Marshall, author of The Good Dating Guide.
"Younger women are also more liberal. I think they believe it is now expected of them," said Marshall. "People used to work up to a kiss, get a little more intimate and then have sex. Now people seem to go the full hog immediately."
Just how long does Marshall recommend waiting before getting it on?
"I think three or four dates are probably about right," she said. "It's best to get to know your partner before giving everything away."
"Wait and see if you have a good friendship and whether the other person is worth waiting around for. I think this leads to stronger, lasting relationships," said Marshall.
