Not exactly ground breaking but worth a read for those who haven't heard of dopamine and oxytocin.
Before the Pandemic, I was asked by a friend if I wanted to join their Free Hugs event, where we would hug people on request. I'd read somewhere that long hugs can give women oxytocin boosts, so where most of my friends would give 'quick' hugs, I would hug women and whisper softly that I would hug them as long as they hugged me and they could let go at any time. Most of my hugs were five to ten times as long as those by my friends and I would have a line of women waiting to be hugged like that.
Great fun, I found myself a couple of kittens through that.
From that experience, I took up a practice that when my kittens come over to my lair, I help them out of their coat and then give them a long hug to bring up their oxytocin levels. It's marvellous to feel all the tension drain out of their mind and body and how they try to melt into your arms.
Knowing how to bring up women's oxytocin levels is one of the great 'secrets' of successful seducers. Being good at bodywork trumps looks/money/status by a mile, because women are most attracted to how you make them feel.
