[ NSFW! ] How messed up our romantic lives would be in this freaky scenario?

What if the female sex organ is equipped with something called LABIA aka Limited Access Biological Imprinting Attribute-?

Meaning, the vagina remembers the first penis of the guy that a woman fell in love with and penetrated and for the rest of its natural life would only open for that one and only pioneering schlong.

( Btw, thinking this would generate easy going humorous banter. I do acknowledge the difficult issues relating to forced sex but hoping the board wouldn’t go there for now. Remember, it’s only the first guy she falls in love with. Thanks. )
