Pretty fucking interesting. It's a lot of info but I found what I read very readable.

This is a PDF and discusses the prolactin secretions after orgasm (feeling of sexual satisfaction) which I think is especially interesting in considering the 'chaser effect' that a lot of people, myself included, experience after masturbating but DON'T experience after having sex.

"Indeed, we have recently proposed that orgasm- induced prolactin release may be a neuroendocrine reflex for maintaining reproductive functions necessary for fertility, conception and pregnancy. Furthermore, we theorized that prolactin may represent a negative feed- back mechanism whereby this hormone may modify the activity of dopaminergic neurons in the CNS that are regarded as controlling sexual motivation and function."
Lots of strict medical terminology and study results in this but I think some of the conclusions are interesting especially since we already know that more prolactin is released during actual intercourse because of the following study, also a PDF entitled "The post-orgasmic prolactin increase following intercourse is greater than following masturbation and suggests greater satiety".

The Abstract
"Research indicates that prolactin increases following orgasm are involved in a feedback loop that serves to decrease arousal through inhibitory central dopaminergic and probably peripheral processes. The magnitude of post-orgasmic prolactin increase is thus a neurohormonal index of sexual satiety. Using data from three studies of men and women engaging in masturbation or penile–vaginal intercourse to orgasm in the laboratory, we report that for both sexes (adjusted for prolactin changes in a non-sexual control condition), the magnitude of prolactin increase following intercourse is 400% greater than that following masturbation. The results are interpreted as an indication of intercourse being more physiologically satisfying than masturbation, and discussed in light of prior research reporting greater physiological and psychological benefits associated with coitus than with any other sexual activities."
