But now (and for the past few years) Neptune, the most spiritual of all the planets, is in your 8th house of transformation and regeneration. This, as was mentioned, spiritualizes the sex life and is made at a higher, healthier and better level.

The erotic force, the sexual act, is enclosed in a position of much more than just physical ecstasy. It can heal. It can be receptive powers of the mind. It not only creates physical babies but can create mental and emotional babies as well – new projects, businesses or institutions. And, if used correctly, can actually put forward a person closer to the Divine – it can bring spiritual illumination. So what is happening now is the elevation of the sexual act from mere animal lust to an act of worship.
Leos become eager candidates for systems like Kundalini Yoga, Tantra Yoga, carissa or Hermetic Science. All of these deals with the spiritualization of the sexual force. It is good to read all you can about these things.

They have no influence on negative energy vibrations. Nonetheless, with spiritual practice, the entire energy vibration of the action can be changed, and thus sex, will be safer.
