Threesomes, foursomes and moresomes

Is three always a crowd? It was the French who seemed to invent the concept of the Ménage à trois, although today it’s not uncommon to end up with something more like a menagerie. They can be fun, but all players need to have strong constitutions, vulnerability, and jealousy can often spring out of nowhere and with threesomes there’s always the danger of feeling left out.
