So I might be popping in to make some comments or ask questions in the future, and I reckon it is only fair if I say a few words about myself, even if I am very shy and afraid of revealing too much about me (as if you could not guess from the name I have chosen).
So, a few quick words about my vital statistics, I am an adult male, still consider myself young despite having long completed school, and despite being a university graduate I am still more comfortable with the word boy than with man, even though I am too old for some bystander to use the term boy non-mockingly. I live in the German-speaking parts of central Europe.
Honestly, my relationship with chastity is a pretty mixed one that probably ends up straddling the boundary between fetish and serious lifestyle choice a little. I probably qualify as some form of asexual, having no interest in finding a partner. Bondage has been a turn-on though as far as I can think back, and it was through that interest that I was originally exposed to the subject of chastity devices as a teen.
But on the other side of the spectrum, I do not really get a kick out of dominance and submission. I do not want to hold anyone's keys, nor be under anyone else's lock and key. My sexual interests do not really include any play with a partner, so there is no point in using chastity as an accessory for couples' play. I would have been perfectly content just treating bondage and chastity devices as fantasy material, except...
And that is where the serious part comes in. Asexuals are a fairly diverse bunch so you cannot necessarily apply one person's experiences to another easily enough, but for me, sexual stimulation has become pretty much a thing to do out of boredom at times. Nothing entertaining at hand? Well, just reach between the legs and there is something that keeps you busy and feels nice. But the thing is, once that becomes habit, the "feels nice" gets relativized a lot, it starts feeling more mechanical. And it can be a serious exercise in willpower to abstain - yet when I am distracted enough, there is no problem in going without for a week or so.
So, I am trying to use devices not so much as a barrier against deliberate effort, but more as a willpower aid, ensuring that it actually takes some effort to choose that particular form of entertainment. Make sure I actually want to do it, rather than just defaulting to it because it is available, and turn "somewhere between once a week and once every few weeks" into the new norm. Quality over quantity. I keep the keys, but I do not have them at hand in bed or at my PC, so if I want unimpeded access, the least I need to do is get up and grab it. Which allows me to reevaluate whether I actually want to go ahead or I am just taking the path of least resistance.
