Sex with no feelings or emotions involved
Seems to me there are a lot of people coming here who have formerly IDed as swingers, but found themselves falling in love with a partner, which then causes jealousy in their primary.
There must be swingers out there who are able to keep emotions out of sex, for extended periods of time. I guess we wouldn't see them here, though. Maybe it is easier for men, who are trained to ignore their emotions almost from birth.
But it seems biology is against those that attempt swinging, FWBs, NSAs, and even unicorn type arrangements. It's well known that having sex with someone causes a release of oxytocin, which is the primary hormone involved in mammal bonding. How can we fight nature?
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
