Why do men believe that they deserve younger partners -- even decades younger. I do not want to characterize all men this way; I have dated men younger than I and lived with one for 15 years.

Yet, over and over, we see men dating and marrying women young enough to be a daughter or granddaughter. Clint Eastwood, for example, married a 30-something TV reporter and started a new family, and often casts himself as a lover for much younger actresses. Tony Randall, in his 70s, started a family with a 30-something women.

We see this pattern over and over. Personally, I find it find of yukky to think of being sexually intimate with someone young enough to be my grandchild, too close to incest. I know some men who feel the same way, not to mention the challenges of communicating with someone who doesn't share one's experiences of life and may be very naive.

I'm wondering where men get the idea that they deserve women who are so much younger than they. What do you think?
