sexpension of disbelief

An IMPLICIT call on long-past sexual-favours for current or future moral-support which may run counter to the inclinations of all but a minority in the group.

-- Okay, so, like you know how, formerly, people might have many kids to insure for some old-age security?

-- Yeah.

-- Whereas now we have pensions...

-- Okay....

-- So it isn't procreation anymore which provides benefits, but sex itself.

-- Ah-ha, so a broad network of past lovers with hope translates into a large network of friends.

-- Exactly. Benefits lead to friends, and friends can be called-on for help and moral-support even when it's challenging for them at-times.

-- Ah-ha, a sexpension of disbelief!!
