I've been studding PTSD and in my exploring
happened upon oxytocin.

I can not help but be curious at to what happens to
the oxytocin levels in people who engage in age play.
And more so those who are lucky enough to engage in
age play with a partner.

Here is a TED Talk on it
Paul Zak: Trust, morality - and oxytocin
If you go 2min and 30 sec into it I promise it gets interesting.
It's more interesting than the text below.

And here is a little info on what it is.


Oxytocin (Oxt) (pron.: /ˌɒksɨˈtoʊsɪn/) is a mammalian neurohypophysial hormone that acts primarily as a neuromodulator in the brain.

Oxytocin is best known for its roles in sexual reproduction,
in particular during and after childbirth. It is released in large amounts
after distension of the cervix and uterus during labor, facilitating birth, maternal bonding, and, after stimulation of the nipples, breastfeeding.
Both childbirth and milk ejection result from positive feedback mechanisms.

Recent studies (2009) have begun to investigate oxytocin's role in
various behaviors, including orgasm, social recognition, pair bonding,
anxiety, and maternal behaviors.[2] For this reason, it is sometimes
referred to as the "love hormone".

However, oxytocin is not strictly associated
with positive social interaction. For example, there is some evidence that oxytocin promotes 'tribal' behaviour, incorporating the trust and empathy
of in-groups with their suspicion and rejection of outsiders.[3]. Furthermore,
genetic differences in the oxytocin receptor gene (OXTR) have been associated with maladaptive social traits such as aggressive
