Personal ads - Looking for a keyholder or sub? discussion

I know that the very label of ‘Keyholder for newbie’ is enough to deter most people, but I decided it was best to start off with total honesty. I’m not a newcomer to chastity by any means; I’ve been experimenting for several years now, yet I am entirely new to having someone hold my key. The longest period I’ve worn my CB6000 is roughly two days, and I want to move on to longer durations. My fantasies revolve around being forced into it for much more extended times than that. At only 23 years old, which combined with my fresh status in keyholding might put some people off, but I am very serious about my intentions and chastity is my top fetish—I enjoy it far more than just wanking if that gives any hint of what I like. I’m seeking a Mistress who would be interested in trying out keyholding, starting online first and then going wherever the connection leads us. I take good care of myself and am fit, happy to send photos via private message to anyone who responds. Note: I realize this post is mostly about my desires—memes and such—but it’s essentially a classified ad at heart; ultimately, I’m looking for someone who is also seeking someone like me. As the submissive in the dynamic, I know well that my focus should be more on my Mistress.
