Today is Sunday. Parents were free.
Reading the fourm for a while, and a few helpful souls pushing me to make a better deal with my parents, I decided to ask. From the way I write it might seem it went down like a business deal but I'm not the best story/experience teller.
I asked them what thier ultimate goal was. They mentioned the same I did before in this forum - pre-marital sex, excessive masturbation. I said I agree with them, but I would like a bit more freedom with my belt either in the form of longer showers on a weekend perhaps or more frequent unblockings. I could kind of feel it becoming awkward, but I just wanted to try my luck. My dad did bring up my previous issues with playing with myself for a long time and how it would affect my time I would be able to spend on my business/ life in general but apart from that there were only a few off hand comments on how I might go back to my old habits (which I did say back about how I was mature now)
So, the outcome. Not going into much detail about my sister, it's still no school (summer break of sorts) for my sister, she is at home with me, still belted. So my mum asked me if I would keep wearing it till my sister starts school again so as to not make her feel singled out. I was okay with that, i wouldn't feel good if only I had to wear the belt while my sis didn't.
The real outcome that they promised is longer showers on weekends (nice) and promised once in a month unbeltings, if I am able to control my self (pretty sure I can), they said we can do perhaps 2 a month (very nice).
The conversation was just between my parents and me so I think my sister doesn't know about it yet, not quite sure how she will react. Once school starts I'm sure she won't be made to wear the belt (I wasn't, because it's a hassle for them to put it on and off daily) But I'll try to explain it to her.
I would really like to thank the members who interacted with me to kind of push me to discuss this with them.
TLDR: I talked to my parents, i am - will be - in a better situation now. Hopefully a even better situation in the future.
