Yes, I'm a fan too. I have a pink resin cage that is only in 2 parts so very easy to use.
I have a box with a time lock on it so I sometimes throw the keys in there and lock myself away all day. The longest I've gone is only about 10 hours though.
There's something really sissy about it I like, even though I don't have anyone else to appreciate it. Especially when I go to the bathroom and have to sit down to pee.

I have 2...a pink plastic cage and a metal cage that looks sorta like a bird cage. I wear them regularly. The metal one is much easier to get on but more noticeable under my clothing. The pink one is very snug and requires lube to get it on.

I have worn both while out running errands and it is so hot. The longest I have worn them is about 8 hours. I don't have a key holder either but have worn them for hookups. Those guys have really liked seeing me caged. Would love to findsomeone to hold the key overnight sometime. It would be interesting to see how I keep my wife (she doesn't know about my activities) from seeing it.

My wife is just starting to learn about my new likes, it I haven’t shown her the cage yet. I do have a key up out of the way in her closet though. Maybe she’ll find it one of these days. Or maybe I’ll just give her one to hold and then see how long it takes her to figure out what it is for. She loves when I wear lingerie so we’ll see what she thinks about the cage.

have done it a few times ,

Not just no but HELL no! "Free Willy" is not just some dumb movie about dolphins.............

I have three different cages and when it’s sissy time, wearing a cage really adds to the experience and helpful when trying to achieve a sissygasm.
A few times I’ve put a cage on in the morning and wore it under my work clothes. Not having a discreet way of removing it during the day forces me to wear it all day. By the time I get home, I’m dripping with sexual excitement.
One day I may have a key holder…sounds exciting but for now I just play out that fantasy in my head

I've done the same with wearing two different ones while working. It's not as restrictive for me though because I work from home. I just make sure to put the key somewhere that is pretty hard to get to after locking up. I have gone out to a store one time with one on. It was super exciting for me. I've thought about sharing with my wife a few different times but when the time comes around I don't go through with it.

Yes i wear my cage even though I do not have a key holder and do the same of making the key hard to get to have worn al day when out but mosty so it while watchg porn and riding my dildo do i dont stroek or touch my cock and can focus ore on the feelings form my ass

I love being caged! There's something about being caged that creates a constant state of sexual arousal. I will often also wear a plug to increase my arousal. Sometimes it's fun to wear my estim cage along with my Lush 2 when I'm out shopping for lingerie or new shoes. But I digress... I have several cages and I love them all. Two are stainless steel, one is a tiny pink silicone cage, another is a hard plastic inverted micro cage, and of course, there is my estim cage.

I don't do it for super long periods of time but I'm discovering that I do too! I haven't found the perfect fit yet but I'm definitely working on it. It is sooo hot to be caged and have a plug in, preferably one that vibrates, moves, or both. I've worn both when shopping at the local adult store. I much prefer to shop in person than online. It's exciting to me to shop and have people there know what I'm buying. I don't go super small but definitely like it snug enough to restrain. I'm still working on the best fit for my balls though. I don't know why but my left one likes to sneak though and it's really annoying to try to get it back in. I hate when I have to unlock to do it. I actually have a silicon one on right now. I use a regular ring though since it fits. It's just more comfortable than the rings that came with it.

I finally shared my little secret with the wife. I gave her the key but didn't tell her what it was for, only hinting that it was time to head to the bedroom. While she was in the room I went ahead and wrapped up what little work I had left, at least as far as she knew, and then headed back to the bedroom to join her. What I was really doing was ditching the regular clothes that I was wearing so I could go in with just my lingerie on. I'm really lucky because she actually likes when I wear lingerie, and she was intrigued to find out what the key was for. I wasn't disappointed to find that she had gotten changed as well. We were both in sexy little outfits, one key difference being that I had my pink cage on underneath. We started playing around, her asking what the key was for. It didn't take long for her hand to find its way to my groin, only to find something hard where she would normally feel my firm, yet soft package instead. That's when I showed her what it was. I'm excited to say that she was even more turned on by it. Now I just have to figure out how to keep her from getting so excited that she wants to take it off too soon. Even after I eat her out and give her a couple good orgasms she still wants to let me out. What I really want is for her to tease me and make me beg for release. It's getting better though. Last time she licked and probed my ass for a good while before unlocking me. I was getting close to having a nice prostate orgasm but I needed something a little different to make it happen and it was more effort than I wanted to expend at the time. I let her unlock me and ride me instead.
