I wrote an article about this a while back. The limited studies on pair bonding in humans have proven that the concept is largely bullshit, but that if the whole oxytocin release is anything to go on—it’s not a reserve you run out of irrespective of gender, and men release MORE of it than women in sex!
Speaking just for me, I didn’t feel emotional connection in sex until I was over 30. I wasn’t open to it my entire twenties, I also just wanted to get laid and have fun then. Which a lot of people do!
Please, they should meet all the women I’ve known who got married after one night stands at punk and hardcore shows.
