I believe that is the truth in submission but not only there.. The greatest pleasure is to know you make the one you love feel happy. As I say and believe people miss the point of sex and of relationships.
It is not something to take pleasure but to give pleasure. When it comes to sex, or any other activity, we should not be selfish. First we need to care for our partner trusting that our partner does the same for us.
In that way eventually and hopefully we will take the most just because we give the most.
