I'm a male switch and I've never really had a dominant partner. I don't know if my femdom interests are purely just a matter of low self esteem, too much time, or the desire to find the next thrill, or a combo of all of them, or perhaps something else I don't fully comprehend. I tend to go from being submissive to dominant, not really shameful or regretful about either but not being solely devoted to one or the other either. I've had a couple of girls into some light submissive play, tying down, spanking, name calling, dirty talk, costume play, that sort of thing, but haven't had a dom in my life. Unfortunately IRL doms and I don't tend to work well together, I'm not interested in being a full time sub and they're not interested in being a part time dom. I'm not exactly Brad Pitt, so those that might be willing can probably find more attractive partners. Ultimately my interests are purely part time, sex oriented rather than lifetime oriented.
That being said for my birthday I bought myself a few items, one included is a chastity belt, this one in particular
http://www.amazon.com/Popular-Stainless-Chastity-Device-Restraint/dp/B00J1YS44K/ref=sr_1_32?s=hpc&ie=UTF8&qid=1423747808&sr=1-32&I'm not the most well endowed guy but it is still a tight fit with the 2 inch diamter, they make 1 inch ones that I imagine must be terrible unless you’re especially small. I use the device typically while either listening to erotic hypnosis or while using a butt plug to massage my prostate, or both, though sometimes I use a dildo while watching porn as well. I am able to orgasm anally, or at least experience a similar sensation through prostate stimulation, though it’s not the only way I cum.
Ultimately it's too large and cumbersome to be an everyday thing, it looks like I took a shirt and stuffed it down my pants. It’s not comfortable but I suppose it’s a feature, not a bug. I like it for masturbation, I'd even enjoy having a partner to enjoy it with, but I couldn't see doing it as a lifetime thing, or wearing it much in public as it either looks bad or is uncomfortable.
It's a fun sex toy for what it is. I'd recommend using a condom as any attempts to get hard will force your skin against tight metal walls of the device. A drop or two of lube inside the condom wouldn't hurt either, but there may be those into pain.
A chastity device is more about the symbolic, I've found myself, quite unintentionally, able to pull myself out of the device without much difficulty. Pull may not be the right word, fall out of, is probably closer. Ultimately the permanent aspect of it is like everything in dom/sub relationships, the submissive has the control in the relationship as to whether or not they'd like to actually do it, the idea of being locked up and having your orgasm controlled has to be something that the sub wants to do more than what the dom wants. And in the end enough friction inside the cage or vibration with a massager will result in an orgasm, at least in my case. But I’m the kind of person with the patience to orgasm anally, and I routinely go days or a week or so without masturbating so the unable to masturbate aspect is not as big of a thing for me, but each until thine own. If you masturbate twice a day, everyday (hey I was one of those guys for a long time) then you may get more out of this. Or less perhaps, depending on perspective.
tl;dr a fun sex toy if you’re into it but not for lifestyle subs
