Online chastity and self locking discussion

I’m a guy in the submissive role who shares the common affection for chastity and denial found here. My partner does lock me up now and then, usually just to tease me in the evenings, but even though I’ve made it clear what I really want, she doesn’t push further. I respect that this isn’t her main interest; one thing she does enjoy is making fun of my size, always insisting I wear a cock sleeve or strap-on when we have sex, which leaves me wondering why she won’t fully embrace my need for chastity—it’s not like she’d miss having my penis inside her.

So, right or wrong, I’ve started searching online for a dominant woman who might ‘scratch that itch’. Realistically, I don’t need a full-blown keyholder. I just want a lady who understands discretion and isn’t too demanding, offering simple chastity tasks lasting 36 to 48 hours (which I can explain away as self-locking). The proof would be using serial-numbered plastic locks on my cage; some humiliation and being forced to wear panties would also be ideal. Am I being needy? Maybe. Can anyone out there fit that description? Not really.

My main question is: am I asking too much? Are there real women who do this without the usual demands for ‘tributes’, ‘gifts’, or sending me their Amazon wishlists? Is it unreasonable to look for someone who just wants a guy to submit to her, purely for the joy of having her own sub? Perhaps I’m chasing the holy grail, but I’d love thoughts from those who might have had more luck than me.

I’ve learned that you don’t get something for nothing. Also, for a female domme, finding a sub is incredibly easy. Unless they are seeking a sub who won't be making demands on her or trying to manipulate her, or use her as a prop for his 'perfect' fantasies.
