And no, I am not complaining at all!
But after being married for 33 years, my wife and I are having more sex than when we first started getting intimate. More frequently and with zero inhibitions. Everything is fine. Just do what you want to do and if it feels good, then do it again!
But as an example, back in the day, if I had already penetrated her, sucking my dick afterwards was out of the question because it smelled like pussy to her.
But now rimming, anal, pegging, cream pie eating, etc is part of our sex routine. Hell, now she doesn't care where my cock has been because she'll suck it!
Life truly begins after 50! (In her case 60)
