So, if sex is also one of the 84,000 methods to practice, why didn't the Buddha ever mention it? He even told people, try not to follow the lustful temptation. Because He knew it is very dangerous. I've also written here. "It's a dangerous way because you could be entangled in its powerful pleasure and can't reach your goal, or even forget it altogether. In this physical world, sex is the most common, yet the most powerful force to reach enlightenment." It even can create human beings! Imagine how more powerful can any other power be! Create maybe not just one human, but many humans; create the whole world as you see it. Keep yourself busy if you are bothered by that powerful force of nature that was imparted within your being as one of the enlightening methods. Just be busy. Help others instead of thinking of yourself too much. If any desirous thoughts creep up in your mind, you cut, cut, cut. Think of something else, recite the Five (Holy) Names. Try as best as you can. Because this physical pleasure not only entangles you in a lower type of energy, but also expends your energy too much. Therefore, I mentioned all the Saints, they practice abstinence.
