OXYTOCIN!! You may know it as the 'Love hormone'. It is a neurotransmitter and is produced in the hypothalamus (which sits in the base of the brain). It is my favourite hormone as it brings so much good; it’s even released during childbirth and breastfeeding. Building empathy and trust in relationships. To....of course....being released through sexual activity and orgasms! One way of doing thanks through nipple play. That is for people of all genders! Though women tend to have a higher level. If you're with a partner and seeing a positive physiological and emotional reaction, you are getting that oxytocin moving from their hypothalamus into their blood stream!
