OK girls, here goes.......

My wife of 35+ years is now post menopause at age 54. All of our marriage I would describe her as disinterested in sex unless I initiated it. She rarely was the aggressor, it was always me. Now things have come full circle. She is the aggressive one. Wants it all the time in any place or way. I mean things that are way out of her character. It is like she was in a locked room in the sex department and has now found her way out. Sex in the woods, sex in front of the campfire, on the table, in the truck, constantly grabbing me on the sly, etc. Don't get me wrong, I LOVE IT, she is wearing me out. My question is why now? We were on the verge of splitting up and then this big turn around.
It isn't an act either but, I feel like any minute she will change back to the old wife that sat in front of the tv and watched HGTV all night. She now takes walks, is losing weight, rides her bike and goes out with friends for dancing and drinks. I am not the jealous type so I don't mind it at all. I am just stunned, amazed, happy, can't believe my luck, etc. Any of you ladies out there have this happen to you?

Another stunner is she has become flirtatous with other men, although she said she would never have sex with anyone else but me. I can't contain my happiness, this is what I have always wanted. One last question....will it last?
