This is so unbelievably beautiful. You know what? If someone told me they were going to talk to me like that during sex, yes, I'd guess that I would find it cheesy and corny. But when I read it, I could FEEL you sincerity, and it made me realize that if someone talked to me like that, I would full-on lose control. I would not find it cheesy or corny AT ALL. It's stunning and transformative.
This is all sex magic. Tantra. Old, ancient stuff you're talking about. Worshipping the Lifeforce, the power of Creation through sex. I think it's 100% real and am not surprised you are finding yourself having these explorations. <3
