I have many years experience as a Tantric sexual practitioner. It would probably be considered Neo-Tantric as I don't get into historical jargon. What I do is real world skill development in regards to male ejaculation control. When you as a man learn how to control the urge to ejaculate a new world of what I call True Sexual Power will open up for you. To the point where you will eventually not want to spill your sacred seed at all.
