As a result, according to Fieldman, "it’s very possible that a new selective process will be take place", albeit one which may take hundreds if not thousands of years.
In fact, Fieldman suggests that one day men may find women who have already had children hugely attractive because they show actual fertility – the ability to reproduce – rather than the potential fertility of the fecund twentysomething.
If we want to lose weight, we might forgo that dish of ice cream, even though we desire it," Buss says.

This doesn’t mean that 40 year old men want to MARRY that 20 year old woman, only that they find her the most physically appealing.To tell men NOT to feel this way would be akin to telling them not to breathe.If we use our technology to separate that natural process, we can have lots of fun and sex without having the baby’.’ In other words, there’s a glitch in the system.Men are still programmed to sexually desire young women, but that desire isn’t bearing fruit due to contraception.‘[However] the sex drive evolved in a contraception free environment.As we’ve learned more about ourselves, and more about how reproduction works, we’ve said ‘Hang on, we can cleave the usual linkage between sexual activity and having babies.
