I have more sex with my partner if she’s got another partner as well, variety is the spice and all that.
So even taking your statement as a given (because I have no real dispute with it, it seems pretty consistent with my experience) there are other factors at play.
The hormone vasopressin, which can be released during sexual intercourse, has a 100% correlation with pair-bonding in prairie voles. The gene that codes for vasopressin release during sex completely determines whether or not voles will form permanent pair-bonds. There is also research demonstrating a link between vasopressin and pair-bonding in humans, though of course the link is much less strong. Oyxtocin is also believed to play a role in human pair-bonding, and it is likewise released during sex.
