Loneliness and long term versus libido

It seems like there's some trade-off between loneliness and libido, in a way that I didn't feel when I was younger. For quite a few years I wanted to f**k as many hot chicks as possible, as often as I could, and when I did that, it was good. Body, soul, and psyche in perfect alignment. I still want to do that, but there is an undercurrent of loneliness and melancholy to random hookups, even with really hot chicks (some of me going on about the subject, here, here, probably some other spots too). That means I should seek something longer term, right?

Then... there is the libido thing... when I see or worse interact with a hot chick, I still want to f**k her. There are some ways to try and minimize the distinction between them... but I don't think they're going away, as a trade off.

I don't have the typical 2,000 words of elaboration on the theme... it's just a feeling that I've had for a while. Life is about contending with problems, not about ease. When I think about the long term, I want companionship. When I think about the next hour, I want a hot wet naked chick writhing underneath me. I think about some of the gorgeous and wonderful women I had writhing underneath me five or seven years ago, and I can barely remember some of them, in some cases. Their effect on the current life is almost zero.
