Tantra says do not try to escape; there is no escape possible. Rather, use nature itself to transcend. Don't fight: accept nature in order to transcend it. If this communion with your beloved or your lover is prolonged with no end in mind, then you can just remain in the beginning. Excitement is energy. You can lose it; you can come to a peak. Then the energy is lost and a depression will follow, a weakness will follow. You may take it as relaxation, but it is negative.
Tantra gives you a dimension of a higher relaxation which is positive. Both partners melting with each other give vital energy to each other. They become a circle, and their energy begins to move in a circle. They are giving life to each other, renewing life. No energy is lost. Rather, more energy is gained because through the contact with the opposite sex your every cell is challenged, excited. And if you can merge into that excitement without leading it to a peak, if you can remain in the beginning without becoming hot, just remaining warm, then those two "warmths" will meet and you can prolong the act for a very long time. With no ejaculation, with no throwing energy out, it becomes a meditation, and through it you become whole. Through it your split personality is no more split: it is bridged.
All neurosis is a "splitness." If you are bridged again, you become again a child -- innocent. And once you know this innocence you can go on behaving in your society as it requires. But now this behavior is just a drama, an acting. You are not involved in it. It is a requirement, so you do it. But you are not in it; you are just acting.
You will have to use unreal faces because you live in an unreal world; otherwise the world will crush you and kill you. We have killed many real faces. We crucified Jesus because he started behaving like a real man. The unreal society will not tolerate it. We poisoned Socrates because he started behaving like a real man. Behave as the society requires; do not create unnecessary troubles for yourself and others. But once you know your real being and the wholeness, the unreal society cannot drive you neurotic; it cannot make you mad.
