I am not attempting to deny your experience. All expressions of experience occur through concepts. Language is impossible without symbolic content, which are concepts.
There are different ways to use the sexual energy and anyone has the freedom to chose. Yet, the doctrine is very clear, and our experience is also very clear on the topic.
I know many people who, after expressing their anger, feel more energized and induce further anger. I know people who feel complete satiation with vanity, and it makes them feel alive, and furthers their capacity to feel deeper and powerful levels of that type of experience. What is lost is the free consciousness, and what grows is the ego. I agree that orgasm can produce more powerful sensations as all the conduits of energy open towards that direction, and that there techniques to maximize and repeat it. What we are stating is that regardless, it cannot awaken the consciousness in the positive fashion and it cannot contribute towards self-realization.
Actually, sexual magic is even more than eliminating both orgasm and ejaculation. That is beginning, but really the couple must even fight against the identification of lust. A couple can be completely chaste physically, yet, if they passionately enjoy sex, they are fornicating in their mind. Thus, their chakras turn counter-clockwise and this activity only helps to awaken their consciousness in desire. The final endpoint of that is an awakened black magician, a demon, etc.
Concerning global domination, the only safety that one can have is to acquire domination over one's own mind. We all have karma, and eventually we will all die. If we are not awakened at that point, then, we will continue to be in bondage, even if the world is a living paradise. The best thing we can do is work to awaken, and to help others to do the same.
