My wife and I are certainly "mature", although she might not apply that word to me.... We met about 13 years ago, and soon planned a getaway.
She wore a beautiful short satin nightie, for our first overnight, (apparently picked out with help from her 2 sisters). I was so horny I must have almost ripped it off, because I failed to comment on it, and it was much later that she told me about my hurry to "throw her on the bed" and get to it. She has worn it since, and it is a pretty thing.
The most bizarre example of this topic I can recall, came a few years ago, when my broadminded daughter took me into an "Adult" store and told me to buy a very flimsy top with a thong panty bottom. My mature wife finally wore it with, I think, some trepidation. I was completely blown away. Her pubic hair was very visible, and that was a huge turn-on for me.
So, yes, by all means, all mature ladies should buy, or get their partners to buy, sexy lingerie. It works.
