Do you think that many sexual escapades between two lovers, occur on the sperm of the moment?

I have known couples who engage themselves in sex to get over boredom.
They have sex when they have nothing better to do!
This is different from recreational sex as we know it.
It is not even passionate sex.
You could very well call it sex at the 'sperm' of the moment.
It usually tires the man out, but the women do not show any appreciable difference in energy levels.
