Ah, the mysteries of the human mind: it turns out that what really makes us jealous is not the "marathon Kama Sutra", but those small gestures of everyday intimacy, like walking hand in hand in the street. It seems that what really hurts is the shared normality, that feeling of being replaced in the most banal, but also the most significant. Because, in the end, sex is easy to imagine... but finding someone you want to walk hand in hand with to the supermarket, that is really strange. Many people don't understand it, but it is true, swinging does not mean sharing love, only sharing sex. It is not about polyamory but about polysex.
