Yeah, we know - anything that doesn't meet your personal taste is 'deranged' - LMFAO!
The fact is that the bible was written (or rather started evolving as a collection of folk tales on scrolls) 2000 years ago. The ideas on things like killing and theft still are applicable. Sex? Not so much. Hygiene wasn't as good back then. Knowledge of different sexual techniques was limited. Now we can test each other and responsible people, once tested, can enjoy an occasional walk on the wild side. Like Jimmy Buffet sand years ago, "Dive in, guzzle gin, commit a little mortal sin, it's good for the soul."
I'm not talking about wild, unprotected sex with random, unvetted strangers, I'm talking consensual, enjoyable experiences with like minded adults who are known to be disease free. Do you have the same thing for dinner every night? Hell no. You try something else now and then - it doesn't breakup your marriage, it's just a very cool, sex positive thing to do IF (and only if) you have a SOLID relationship w/ your significant other.
Let's face it Sparky, when we're dead, we're dead. Ever been under general anesthesia? Samo, samo except your heartbeat (in addition to your brainwaves) is flatlined. You don't know you're dead because the brain (where knowledge occurs) isn't functioning.
I suggest you search for the 'Hidden Psalms'. Like Psalm LVlll - "Goeth out, lie in the cool grass I have created foir you an know her." That alone tells it like it is because, back then, to 'know someone' was to be se*ually intimate with them and Jesus Okayed it, he just did so in a quiet way and the Lost Psalms only recently came to light in 1th century Europe.
So Sparky, have a talk w/ wifey. My guess is she already wants to try this, just doesn't want to hurt your feelings.
Peace out,
