Oh boy, what an half-ignorant. You're telling me that I have never heard of Kinsey? Sorry, it's too late for you to suggest me to read Kinsey book because I already have over a decade ago...even there has a film based on a story about him. He had an experience an open marriage relationship....and dammit I ain't following his suggestion based on that. He even had an experiment with another male....of course I found it disgusting.
You still deny that those relatives and family friends of mine who are long-time married who are, as matter of fact, no longer sexually active...well fine, so be it all you want. If my grandmother, my ex's mother, my best friend's grandmother, and my S.O.'s grandmother wouldn't tell you their secret that they're still sexually active...then they would have remarried a new husband after all of their first husbands are deceased for more than a decade ago...speaking of your quote "old people that still have hormones that are hard to go away"....
Get real.
