Define Your Specific Kind Of Chastity

I am pretty new to chastity and forums. Based on what I have read online, our version of chastity doesn’t seem very similar to others. We just practice chastity. There is no D/s, cuckolding, or addressing her as Mistress. I simply handed over control of my penis; she didn’t take ownership of it. Since she seems to enjoy it, I am happy to continue this way. My wife is naturally a people pleaser who finds joy in giving pleasure to others. There is no changing that nature and believe me, I have tried. I am very alpha, perhaps too much so. It might seem odd having my wife control my penis while she also serves dinner and handles most household chores, with a few exceptions. But it isn’t difficult for us because we have been involved in BDSM for about 45 years. I like being sexually submissive as stress relief, and she likes dominating me during sex. She gets excited calling the shots during intercourse and loves teasing me before telling me to lock it up. It works for us much like our previous BDSM arrangement did. Am I alone in having just a Chastity lifestyle? Do most of you use chastity as part of a larger fetish? There is a British website that seems to have many self-described “Sissys”. Some websites feature guys into cuckolding as a fantasy. The same applies to Femdom, D/s and similar sites. Does anyone have an idea where chastity is most popular? I cannot quite grasp this fetish since it is practiced differently all over the internet. I do understand that chastity can stand on its own or be part of a larger fetish, but my impression is that it is used as part of another fetish the majority of the time. I also get the feeling that it is much more popular in Europe than in the States. I know many kinky people and not one of them is into chastity. They all think I am the odd one out, even from those involved in some really heavy duty stuff.:)
