Dr. Ruth Westheimer always said that the sexiest part of anybody’s body.
To accomplish self-control, the seeker is taught even in the midst of enjoyment to direct that sense of enjoyment upward to the brain. He should try to feel that sensory pleasure is feeding his inner joy at its source in the Self.
The joy in sex shouldn’t just be about the physical, but the spiritual, too.
Tall order, I know, but it can be done.
