Chastity is more than denial, it's tranformational

I've been thinking a while why I'm turned on by subs in chastity. It's more than the physical: for sure, I think that a neat and small device on a sub makes them look significantly sexier, seeing it their underwear, giving a clear defined shape to their denied manhood.  When browsing through social media, it's so hot to see teh gym selfies of a sub in chastity, straddling the line of discretion and recognition of their sub status.

Yet, there's more to it, I belive.  My experience with chastity is that it starts to rewire the sub in ways they can't imagine at the beginning.  At first, I can't deny, I love the control - knowing the sub is not able to orgasm without consent and usually at my hands.  Knowing that the sub has put its trust in my hands and surrended themselves to me really does drive me wild.  And when they're gone and you're holding the key, the true sign of your control over them.  It's this journey over time that starts to eat away at the sub. There's the hunger to cum (and may subs never get past this phase), being constantly horny and needing master to let them release.  The true slaves are those that allow this hunger to consume them, to let their service become their identity. They're controlled subs, no longer men with the right to an erection.  This is where you see the sub blossom, where the very throught of an orgasm through their nub begins to feel alien and undesirable.  The only cock that matters is the one that penetrates them.  They worship that cock, their own reduced to an inferior status.  It's here that I find the sub truly accepts their place and finds the peace with their status.

To the other masters, what is your experience?  How does chastity fit with your subs and slaves? 

For the slaves and subs, what happens in your head?  How long can you go without needing to cum?
