News of the video comes as Trump is facing allegations from at least four women that he groped or kissed them without their consent.

"At that time, if the guy was younger, you were considered a pervert."Brings now gravitates toward younger men — the largest disparity was when she was 50 and dating a 25-year-old — because she finds she connects with them better and, frankly, men her own age aren't as interested in her."When I was in my 40s, I realized I had become invisible to men of my own generation," said Brings, co-author of "Older Women, Younger Men: New Options for Love and Romance" (New Horizon Press).

She noticed younger men, often raised by feminist women, were intrigued by and admiring of her success and experience, whereas older men seemed threatened and expected women to play traditional roles.

"I was so ashamed," recalled Brings, now 65 and living in Fort Lauderdale, Fla.

And some studies have shown men and women are happiest in households where the husband is older than the wife. A study published in 2008 in the journal Psychology of Women Quarterly found that women 10 or more years older than their partners report being more satisfied and committed to their relationships than women who are the same age or younger than their partners.
