Of course, there are exceptions. In the Tibetan Nyingmapa tradition, there have been exceptional masters who were married. However, these masters relied as much on the blessings of their yidam, or spiritual guide, as on their personal practice for power.

If you have a supportive spouse or partner who will practice with you, that is an excellent arrangement. That would be a life based on mutual care, respect and love, without over-reliance on sex to define the relationship. Such a life is a good foundation for achieving liberation.
