Free of coercion, means the freedom to say NO.
No one is obligated to give or engage in sex, not even in a relationship or marriage; but this includes the thinking behind the term ”friendzone.”
To me, the idea of ”friendzone” is or may be connected to some odd belief that people mostly women have an obligation to offer sex in return for friendly actions or thoughts. To such thinking I wish to remind people that NO one is required to be sexual with anyone regardless of how nice you are, how close you are as friends, on a date, or if you’re romantically together, etc…
I always strive to respect the body ownership of others including their right to use sexual consent when, how, and with whom they wish and there is no external entitlement nor obligation owed or owned by anyone else than the person themselves.
