Tantric massage. awakening sexual energy

Man have things changed for me in the last few years. I used to be in love with dominant women. To be true I am still a fan. That being said. I have experienced some kind of awakening. Im told its Kundalini. Bottom line. I have been retaining my sperm. The sexual energy runs through me like a full body orgasm. Hands free when I lay down and relax everything. Has anyone else experience this. I feel pleasurable vibrations and see lights and symbols when I close my eyes and relax into it. Its scary , exciting , and confusing.
