Sometimes, regarding sex, a woman asks: “What can I do to please you?” Although any man might like a good back rub, in the end you want to get to the Main Event, and here the answer is always the same: “I want you to have a chain of brain-melting orgasms that leave you a quivering heap of pleasure.” To achieve this, men generally take the active role, and women the passive; or perhaps, as in dancing, both are active in their way, but the man takes the leadership role. Men do to; women are done to. Women are usually pretty happy about this. This is “good sex.” Unfortunately, I think it is rare these days.
From this, you can extend to relationships between men and women in many aspects.
