What is exclusivity?

This entry describes exclusivity as an agreement, spoken or assumed, that the two people are not romantically or sexually involved with anyone else. It notes that the word is often used before anyone has said it, and that dating one person for a while is not the same as that agreement.

What this entry does not do

It does not replace the entry on monogamy or on an open-relationship disagreement, and it does not say when exclusivity must begin.
