This has been asked so many times I’ll just put it out there once again. The below are my personal thoughts about chastity using a device:
When I put a man in chastity, during the situation / scene I get off on the fact he can’t get an erection.
His body will try hard but it’s physically not possible. That’s very similar to other predicament bondage – like a body fighting the ropes, his cock will fight the bars of the cage.
He will be so turnt on, at the same time so frustrated.
I get off on the sweet frustration, I’m weird like that. I like teasing, showing and telling him what he could have if it weren’t for the fact that he’s caged. I love licking and kissing his flesh through the metal bars.
Outside of the situation, I simply find it extremely flattering that he is wearing a cage for me. It is something that to a degree is a limiting factor in his normal life, but he copes with it, for me, because he likes to please me more than he likes the easy life without cage. I like that the cage is an almost constant reminder of me, it cradles his cock like a grip of my hand, and the fact that being chaste and not cumming over a period of time means I’m on his mind almost constantly.
Most of all I love the fact that a man willingly gives up what most think defines him as a man – his cock. He gives up the ability to erect, to masturbate, to fuck, to cum, because I’m more important to him than his carnal desire.
And in exchange I make sure that the quantity of orgasms he’s giving up is outweighed by the quality of the orgasms I grant him.
