About ten years ago, I had a lover who had erectile problems, as he was a lot older than me. I was having some spontaneous experiences of Tantric sex, and on this particular occasion, after helping him orgasm, I got him to put his soft Lingam on my Yoni, while I held him tight on top of me, all chakras connected up to the heart.
I ‘grew’ a large energy lingam from my solar plexus about 12 cm in diameter, and 20 cm long, and moved him as if I were moving in and out of his solar plexus. Oh WOW, I had NEVER felt such exhilaration, and complete whole body pleasure, the equivalent of ten orgasms together!!! When I reached such a height, I got him to start moving in and out of my Yoni with his Lingam (which was now hard again), and the Absolute Bliss was extraordinary!!! WOW you will NEVER be satisfied with plain old sex, or love making ever again, once you experience the heights of Tantra! And those heights keep getting higher!!!!
