If God is omnipresent, every act of sex is really selfcest; everyone having sex is just his multiple-personalities unknowingly masturbating him/themselves/eachother. A more truthful scenario would be more like a transcendent non-human Buddha lucid-dreaming of pure bliss coming direct from the source, welling up from within, a self-induced divine-revelation in the form of a raw stream of infinite/eternal perfection. Definitely worth being jealous about, but jealousy is such a negative emotion. better for us to simply find our own perfections which are more suited to our own present perspectives. Few people are ready to be a buddha. But I get the impression you might want to give it a try for a while. Good Iuck. Sweet dreams. ;-)
But in that case, you could be your own anything.... I would believe you, but you seem to be rather timid, if what you say is true... because you could not only be your own son, but your own grandpa, grandma, mother, and cousin Bob.... NO... YOU SHOULD BE... then it would be incestuous orgies all the time!
DREAM BIGGER, you can do it ;) :P
But I don't have an incest fetish. I just kinda miss my sister who I was caught wrestling with in bed that one time, and we weren't blood-related anyway. But I hear my biological mom was a cute redhead and if she had daughters then maybe I could be incestuous with my half-sisters, but I'm not even trying to go there, and my dad was blonde and I !like blonde girls too, but I'm still not trying to go there. It's hard enough just trying to find someone I can get along with, you know?
