Well, yeah. Humans run the gamut from having a single mono pairing for life to having a constant flurry of new relationships (and others ending). When a culture doesn't allow for that variety to happen and expects only one approach to be acceptable, then there are going to be lots of folks breaking expectations. One size does not fit all.
