Your mind is nirvana.

But deluded people don't realize that their own mind is the Buddha. They keep searching outside.

Buddha means awareness, the awareness of body and mind that prevents evil from arising in either.

Once you see your nature, sex is basically immaterial.

The ignorant mind, with its infinite afflictions, passions, and evils, is rooted in the three poisons. Greed, anger, and delusion.

The mind is the root from which all things grow if you can understand the mind, everything else is included.
