Getting a Strap-On Worn by Me

My wife has decided she wants me to wear a strap-on during sex. Since I want her more involved in our kinky activities and because I’ve liked using one with my submissive partner, I bought one for us. We chose the Doc Johnson vaccu-lock model, which is an upgrade from the basic one I use occasionally (mostly when fingered or fisted) and includes an 8” realistic cock attachment. It’s about half an inch larger than me, though we can swap attachments if needed. After dealing with some swelling and skin irritation, we managed to stop using my standard chastity cage. I’m staying disciplined without masturbating and haven’t had a full orgasm in six months, although I miss it frequently. With my wife, I’ve noticed the strap-on feels better when I keep my CB device on. For those of you who wear them, do you prefer being locked or unlocked?
