I am currently a mid-50yo 24/7 butt plug wearing bi-ish guy. My wife and I enjoy a lot of anal play. She is not anal-only but I have been mostly anal-only since we got married. We agreed to have a female-led relationship and that included, even before we got married, a plug and a chastity cage for me.
I have used butt plugs off and on for 20+ years so it wasn't a big stretch (pun intended) for me to start keeping one in all the time. Obviously except for daily bathroom routine and the occasional medical procedure. Otherwise the plug only comes out when she wants to use a vibrator or strapon.
The chastity was partly to help me break my masturbation habit and partly because I have ED anyway and even viagra and cialis wasn't helping much anymore (diabetes sucks). So, we found other ways to enjoy our sexuality.
I have been into kinky stuff since I was a teenager (mostly dares and streaking back then). I was a Dom for about 10 years after my first marriage ended. I trained several "pets" (both submissive women and a couple of sissies). I got involved with a Mistress for a couple of years when I lived in Seattle and started exploring my submissive side, including my bi-curiosity. After I moved back to my hometown in West Virginia, I met my current wife and opted to continue in a submissive role, though it is not as strict or formal as all that.
So, that's probably way more than everyone needed to know as an introduction.
