Funguy The specific reason she's against masturbation and premarital sex is that she considers it to be very greedy to please yourself or use others to please yourself when you're not commited. And greed is one of the seven deadly sins sooo pretty bad if you ask her. Also the whole thing about lust being a sin makes it also just not allowed at all in our house.
I would think that, leaving lust aside, desire for pleasure is more gluttony than greed, if you are going the seven deadly sins route. It is a case of desiring too much of a good thing. Greed is an evil because it leads to wanting to deprive others of what is theirs - which could be applied to rape, but not to consensual sex or masturbation. But gluttony - losing control of your appetite - is kinda what you have proven to be weak to by getting caught masturbating at someone else's place. You could not wait until you had some proper privacy, you just had to try to get off immediately. Plus masturbation could be seen as a kind of sloth as well, get to enjoy the pleasures of intimacy without having to attract a partner first. I guess that latter one is out now that you have a steady boyfriend though. Your boyfriend could control your gluttony as well, leaving lust as the primary sin the belt may be needed against, if you subscribe to the concept of those sins. But lust can be dissected even more. Does the chastity belt really prevent lust? If anything, lack of sexual relief might increase desire, so you might lust less with regular relief. And is it really lusting if all your love is directed towards your partner, even if you have not entered into a sacramental bond yet? Lust is usually more associated with fleeting desires, constantly changing partners and one-night stands and stuff like that. Again, having your partner keep your desires in line might actually make you less lustful, I would say.
Funguy I honestly could never even just threaten her with that because it would hurt us both, I could get cut off from her support and she'd be hurt emotionally that I would even do that.
I understand, you definitely appear to value your relationship and would not risk that for relief from the belt if you know there is another way out. Still, it might be worth letting you know that you know your rights and that they include the free exploration and development of your sexuality. I do not know how you could bring that up in a friendly and understanding way, or if it would make a difference; I know too little about you. But she should know that you are willing to follow her rules because you are respect her, not because she is entitled to enforce them.
Funguy About the private hygiene breaks she's not interested in seeing me naked lol.
Understandable (though I still maintain there are ways to ensure hygiene breaks are not abused without constantly staring at the person cleaning themselves), but if she knew how you are using that opportunity...
Funguy My bf thinks it's hot because he enjoys being in control in the bedroom and teasing me and having control over when I orgasm, which he would if he had the key but currently he has no control at all. He also thinks it just looks sexy on me.
I cannot say much about the thrill of controlling someone's sexual pleasure, but I do know that chastity devices definitely have a tendency to be a rather attractive fashion accessory, in addition to their primary purpose. So without knowing what you or your belt specifically look like, I understand your boyfriend in that regard.
