Girls only online dating
I'd guess 5-10 years younger than they actually are. I also agree on most of the points about safety and security for women, but men can be scammed and robbed by women purporting to be interested in them. One other point - why does Psy Today allow comments like those posted? It doesn't matter if the picture was taken 5 years ago because it's the same person. The research indicates that men are initially attracted to a women's looks and women are ultimately attracted to a man's income/stability he may provide.
And you neglected to mention that women lie about their age quite often, especially those over 40. I don't know if the relationships last, or why they don't. I go on a LOT of first dates and typically don have second dates... It detracts from your image when you let people advertise in the comments sections. So it's hardly surprising that both try to bend reality in order to entice the "ideal" mate.
Online dating services are now the second most popular way to meet a partner.
The popularity of online dating is being driven by several things, but a major factor is time.
Maybe older people are just more interested in projecting their real self, rather than an imagined or ideal version.
