I think it ads to the chemistry. Because only stunningly beautiful women can seduce younger men, and only highly intelligent men can seduce older women.

Ofcourse there are great couples in various age groups. As long both are adults and consent on the same terms and its for the benefit of both.  Then what others think doesn't really matter.

It is never a problem when it’s the Man being older than the woman so for me it’s not even a discussion here, or if it is it is just patriarchy.
