i think you probably used this kind of magic in an ineffective way. if i wanted to use sex magic in order to look into past lives, i would raise the energy with sex and direct it into a charm of some sort, a candle, stone, or medicine bag. then i would use those charms later to access this intense type of energy during meditation where i could be sufficiently focussed to hold on to and use the energy. what seems to have happened is that you raised alot of energy, got a brief glimpse of a past life, then lost it because you were startled, surprised, and worried whether your husband would notice. sex magic is great for raising high amounts of energy, but if you need that energy for more introspective work such as you're wanting to do, the bed isn't the greatest place for it. so store it in something, put it aside, and use it later.
