Speaking only for myself I find that I want sex just as often (i.e. I think about it all the time) but there is just not the urgency to seek that sex. When I was younger I would grab everything that came up, wherever it came up and was constantly on the hunt, and, boy, did I have a good time ! Now, though, whilst not necessarily more discerning I am not so manic about it, and, as a consequence, life is much easier and the opportunities, when they come knocking, are more savoured and enjoyed.
