One thing that bothers me about a lot of the chastity files is that they all seem to include this feature of removing *interest* in sex. Now I'm sure I speak for many people when I say that's not usually what the chastity scene is about, it's a form of erotic denial, refusing to let someone have what they desperately want. If you take away that want, then you ruin the whole experience.
What I would really like to see is a file that *encourages* arousal, making the victim hard or wet constantly, growing more and more aroused until they masturbate, but then being unable to achieve orgasm. This would be the ultimate psychological chastity device as the victim can still bring themselves to the brink of orgasm but never quite get there, eventually this kind of denial can drive a person crazy.
Such a file would ideally be self triggerable too, perhaps with a period of days first written down or memorized before it becomes locked. I would recommend against it being a curse, as in the heat of the moment it's easy to lose perspective and commit to something you will truly regret.
Another observation I would make is that there are many "become gay" files, often included in feminization categories. This, also, misses the point. In feminization, the allure of forced bi is not in actually being gay, but in the fact that you're *not* gay (and indeed not really a girl) but are being forced into the role of one. There is no humiliation if you are happily conditioned to be gay.
This being the case, a truly wicked file would be one that only allows a person release if they are looking at porn of their own sex, especially if they are not actually gay or bi. The file would make it so that they can only reach orgasm if they do not take their eyes off the porn, so as to prevent retreat into heterosexual fantasies, after making them masturbate for over an hour (or a time of your choosing) and it would *not* include a suggestion of arousal, because the whole point is that they are not turned on by it. (That doesn't mean it should make them feel repulsed though, let the emotions come from the victims themselves.)
An idea like this was used in the fiction story "lesbian pussy" (I think that's the title) which hopefully some of you have read and found as exciting as I did. Although that story did eventually include elements of forced feelings of arousal, that kinda spoiled it for me. The idea of someone being forced to orgasm only in relation to the opposite sex when they are *not* attracted to that sex or aroused by them makes for the most humbling and delightful humiliation.
These two ideas don't have to be part of the same file, in fact it would seem better that they remain separate so people can pick and choose. I do think they would be extremely popular though.
Any feedback is welcomed.
