I'm trying to understand how this process works.

For example, is it the result of the oxytocin released from sex that makes your partner bond with you or is it that your partner associates the oxytocin release with you and thus creates that bond?

Also can some measure of pair-bonding be expected from a partner with a low n-count or is it still a non-guaranteeable occurrence?

Finally, how does the process differ between men and women? If women are more emotionally driven, then can the pair-bonding experience be more likely to occur on the female's side than on the male's?
