What you want may be intimacy. What you may not want is someone entering the rest of your daily life.

Price or relationship cost?

With friends with benefits, there may be no explicit payment, but the relationship itself has to be maintained. With a professional companion, there is a clear price, but there is no requirement to maintain a private relationship between meetings.

The structure can be clear without making the time together cold.

Choose the time when you want it.

Choose whether to meet. Choose who to spend the time with. Say what kind of time you want. Then, when it ends, return to your own everyday life.

You do not have to belong to someone during all the hours when you are apart. This is not about rejecting romance or friends with benefits. It is about allowing yourself to choose the kind of intimacy that fits the life you already value.
