I think of this in the way that I think about Viagra. When you get older you don't want to have to worry about certain things driving you crazy anymore. Why artificially extend the experience?
No disrespect meant, but if I'm reading your post correctly, are you saying that you look forward to the day when your anatomy is no longer able to keep up with your libido? Or perhaps you long for the day when your libido wanes. In either case, you've weakened your case in my eyes. I'll take that sort of distraction any day...:)

Feel the white light, the light within
Be your own disciple, fan the sparks of will
For all of us waiting, your kingdom will come
