Jonas Glad we are on the same page there. No detachment of body parts, the objectionable thing is the penis being so demanding, not it being part of your body. I mean, we could talk about the pros and cons of (male) circumcision in another topic, I am personally not a big fan, but anything beyond that just seems like a big no-no to me.
But sexual freedom, sexual autonomy, or, as German law calls it, sexual self-determination is not just about being free to have sex, but (maybe even more importantly) about being free to not have sex. The German criminal code has, since 1970, defined crimes like rape, sexual harrassment and pimping as "offences against sexual self-determination" (rather than the "crimes against morality" they were before).
Therefore, I believe your choice to not experience sexual relief, and to seek both social and mechanical help against it, is not a violation of your sexual freedom; on the contrary, it is an exercise of your sexual freedom. In a way, it is not so much a "freedom of sex" as it is a "fredom from sex".
Nate At first, when I was locked by my parents, it felt kinda strange ... that your parents say to you something along the lines, "Now you can masturbate, I'll be back in ten minutes and re-lock you.". Of course, I soon got used to it, even for usually having only ten (and sometimes even five) minutes, and that wouldn't be the worst thing.
Urgh... never gave so much thought to this particular aspect of being locked by your parents, but that seems awkward as hell when you are not used to it. I do not think there is a boy in the world who wants his parents to know when they are masturbating. Heck, even the if is a source of major unease often enough (though I guess that was already a foregone conclusion for you at that point). Not sure if I would have managed to pull off a release the first time if that had been my experience. Then again, if that was after your 5-month punishment, you were probably desperate enough to just go through with it.
Nate The most annoying thing is, a cage will prevent you from masturbating, not magically deactivate your penis. It's normal to get an erection - in the morning, most notably; and when you see a hot girl/guy (and you'll see a lot of them at school). This will, of course, be a lot more frequent, as you're always horny and subconsciously try to find sex.
I reckon that the erection not being as visible as on most other boys who get that response was at least small consolation for that, though probably not enough to make up for the discomfort of an erection and the unfulfilled arousal that comes from seeing someone attractive.
One more question that comes to mind, is Jake aware that you are withholding releases you are authorized to give? Because I am just imagining what happens if he finds this forum and reads about that. I mean, I guess the names are changed, they sound awfully English for Czech names, but all the details you dropped, a boy being locked in chastity by his parents, but with the keys now held by his boyfriend, and in turn being a secondary keyholder to his younger brother whose primary keyholder are still the parents... that is a pretty specific story to have, and would probably still be recognizable to the other people in that story.
