BDSM Dating in San Antonio

I’m completely new to BDSM and looking for a woman who is interested in building a dom/sub LTR. My goal is to find a monogamous relationship, but I’m also open to have friends with benefits. I’m mostly looking for someone who is a domme or a dom leaning switch. You can be submissive only as well, as long as you’re looking for a long-term relationship. It’s OK if you’re older than me and I don’t mind dating someone who lives in another country or state. Maximum age is 59.
