A woman will always fondly remember her first lover, largely due to this. In addition, the more partners she has had, the less of this chemical the body releases, because she has "trained" her body to ignore it. So a woman that has had several partners, is literally incapable of forming a real bond with a new partner. Which is why the single most important factor in predicting if a marriage will end in divorce, is how many sexual partners the woman has had before.
