Where do I find masochistic women who want to be owned? ITT:

The local bar. You have described all women.

Try fetlife, obviously.

try fetlife. there are a lot of old/ugly people on there, but if you sort through them you can find some good ones. That's where I met my partner and we lived the bdsm lifestyle 24/7 for over a year. We have a kid now, so it isn't 24/7 anymore, but we still enjoy it in the bedroom.
