You may be more correct than you realize. Back in the 1970s, a study found that swinging was more prevalent among well-to-do Midwesterners, especially in the Minnesota and Wisconsin states, than California. It was assumed that California was the leader in this type of lifestyle, the study proved that was not the case. It's probably tampered off due to HIV and now the Covvie, but given the frequency of caught coaches and politicians hole punching outside their meaningful relationships, i doubt it has tampered down very much. As for nobody cares, well, it's big news each time one of them gets caught. This very thread illustrates that. If it has any legs, expect it to be on major news networks soon enough.
