When two people come together to create an arrangement, each is expecting to have some need adequately satisfied. This means that both parties must be willing to indicate where they stand and what they expect from the other.
When done right, the arrangement is established with a clear outline of how things are expected to progress. The sugar baby can indicate the kind of support that she plans to get financially and otherwise. The sugar daddy can accept this, or he can discuss any alterations he may wish to make.
Similarly, the sugar daddy can indicate everything that he expects the sugar baby to do for him in return. She can then choose to accept his terms, or she can move to discuss any alterations that she deems necessary.
Establishing what is needed and expected in this way allows for a smooth process when the relationship begins.
