Agree with you. As women age, they also realize they can't be as selective and maybe some feel they're running out of time to have sex with younger guys and sadly this is true for many whether it's an older guy with a much younger woman or an older woman with a much younger male. We all have a shelf life when it comes to sex unless we're Hugh Hefner like!
Middle aged women can often be a lot better lovers than women in their 20s in my experiences. Of course, the younger women have the benefit of not having gravity affect them to the extent as the mature ladies. Gravity though is kind when they are horizontal.
