Yet it’s been my experience that couples who negotiate sexual boundaries, like the ones mentioned above, are no less committed than those who keep the gates closed. In fact, it is their desire to make the relationship stronger that leads them to explore other models of long-term love. Rather than expelling the third from the province of matrimony, they grant it a tourist visa. For these couples, fidelity is defined not by sexual exclusivity but by the strength of their commitment. The boundaries aren’t physical but emotional.
