As one who found a SO with a sex drive at least as strong as mine (pre-menopause), you might want to pursue a woman. If she's "interesting", she'll change with your needs (and you with hers). Open relationships, swinging, manage a trois, etc., all becomes available with the right girl. Been there, done that. Her reaching menopause ended everything for me. Tried the escort thing, too risky (and the girls are CRAZY), tried the "affair" thing (had to draw on a husband, fuck that shit), and the single mistress thing (eventually they want you to leave your wife, not happening). AMPS turned out to be the best of both worlds. A nice mix of beautiful women until you find a good one, then pretty decent "relationships" until the INS begins to call. I used to visit DR once a year (big liars, crazy as hell, but BOY OH BOY, and not very expensive).
I am probably not as well-invested as some who posted here, but assets measure well for me to continue as I work toward retirement. In less than a year, I hope to be mortgage-free, which is more cash flow. Unless you have a decent income, investments, or a woman who will work with you, this lifestyle can be extremely expensive. Not at all worth going into debt over.
