That an orgasm never killed anyone but a forced chastity can leave permanent marks in the mind...
How I can convince my daughter(s) to wear a chastity belt
Angelina yes it true yes also so that it is a fact true that I have masturbated. he has caught me doing it and I can not claim it is not true
Yes,as he's against it and caught you in the act,there is no good arguments about it...Especially as I guess he doesn't care it is common for women to do this and that is natural and not harmful to anyone.
Laura once I get released from the belt I will start having sex soon.
Is it true?
it is not harmful, but my father thinks that it can be harmful for the psyche. it was true even before my time in cb so that my father always told me to wait with sexual activities until i get married but unfortunately i couldn't do anything against his feelings and needs 
i don't have this extreme willpower and that's why i'm closed now
Laura Not sure, that's a problem. I'm pretty confident while I'm in the belt.
So maybe it is not totally wrong to make you wear one...
I've no problem with having sex when not married,but as it seeems to not be allowed in your family...
Angelina it is not harmful, but my father thinks that it can be harmful for the psyche. it was true even before my time in cb so that my father always told me to wait with sexual activities until i get married
As far as I know,no recent studies imply that masturbating is harmful for the psyche.It has mainly good effects,as long as it is not excesssive.
In France,for a long time,people thought that masturbating make the one doing it deaf...
Angelina i couldn't do anything against his feelings and needs
It is very hard to resist such urges for long if not prevented to do it...
Vanessa So maybe it is not totally wrong to make you wear one...
Well, probably they have a point. But I agree with @strictfather, they can't do it forever, although they are satisfied with current situation.

well... many things happened in my family in the last weeks:
the friction between the two sisters has increased. my wife is more and more angry with daughter(16). Daughter(16) is in "prison" except for school (and her sister keep and eye when they go together to school: daughter(16) told to the younger sister <<your are their spy>>) an now (the only positive effect) daughter(16) studies more because has nothing to do except study. Her "Friend" is disappeared due to "prison" effect. Darkness lives in the house, bad bad bad situation: Argument is always the focus point at every breakfast and dinner time (also silence speak loud!).
For some time daughter(16) and daughter(15) did not speak each other and only the mother spoke (was very angry). I tried to make them understand where the problem was. No apparent effect.
Then some day later everything came out like a volcano erupting lava all around.
The young sister is afraid that the "bitch" sister punishment will create future limitation also to her and so is angry with the sister (incredible her words <<if you kept your legs closed now i could be more free to go out with my friends>>). This because my wife limited a bit also her freedom, because she in only 15 and for the fear she can follow the sister steps. The daughter(16) hates to be seen as a "bitch" and lives in the nightmare of the chastity belt idea and told us we are mad (!!!) to think to a "torture middle-age thing".
But then my wife explained it was only a "provocation", an "idea" but nothing concrete. But daughter(16) told her she was lying because (oh my god!) she found in computer history some searches for CB. <<ehm... it was me...>> i had to confess, i was just looking about it, just to understand my wife idea (i really didn't know anything CB). it would be better if i had not told that. uuuuu.. the pain..... my daughter(16) attacked me telling that i am working on her back. and she told to me and the mother "if you want me to wear a CB. well... wear you first and give me the key!". my wife became more angry ("daughter, you must respect your mother!") and they started to discuss and argue very hard. And the daughter(15) started to cry <<i will never wear a CB! convince yourself! i know if my sister wear it i will have to wear too, i am clever, i know it will happen>>....
At the end i had to tell all of them "no more with this idiotic CB idea! STOP! deleted. erase the idea!!!! i forbid to think, talk, buying, wearing a CB in this house. NO MORE.".
And i asked them all to go altogether to a family psycologist to tank about situation.
Finally they all agree.
We will see.....
strictfather and she told to me and the mother "if you want me to wear a CB. well... wear you first and give me the key!"
It makes sense, give you the key, not her.
it really seems to be a rather broken situation in your family, I'm very sorry for you. you all made mistakes why i think it's a good idea to do family therapy.
it would be too bad if a family breaks on itself. hope that soon better news will come from you good luck 
Angelina He also means that sex is only with my
partner should be made (in my case camryn) and also only if we are married
Same for me presently.
Laura Well, probably they have a point. But I agree with @strictfather, they can't do it forever, although they are satisfied with current situation.
Right,it can become hard to follow it for too long.However,except if you leave the city or get married,I'm not sure why they would decide to change it.
A lot of talks,and not easy ones,since it started.I hope it'll become better soon.
However,even if if you don't want to suggest chastity again,I noticed it:
strictfather she told to me and the mother "if you want me to wear a CB. well... wear you first and give me the key!".
It was exactly what Ivana did when she decided it would be good for her daughters to wear a chastity belt.She bought one for her,give the keys to her husband and started wearing it.When she convinced her older daughter to wear her,she gave one of her keys and the other one to her husband;in exchange,her daughter gave Ivana one of her keys,and the other one to her father.So,no one have the key to her own belt,and only the husband of Ivan(a and father of the daughters)have all the keys.Even if I don't know if Ivana made copy to give to her second and third daughter.
If your oldest daughter change her mind about chastity ,or hestiated,you could suggest it.
At least,as,since she is in "prison",her friend has lose interest in her,she should know he wasn't interested in her,but only wanting to have sex with her.
Angelina it would be too bad if a family breaks on itself. hope that soon better news will come from you good luck
Yes,it is a very complex situation.Almost everyone is angry to everyone,I imagine it is hard!

Therapy could be best choice... as all here said you since minute 1.
In a context of anger is not possible smooth relationship in the family. I hope you can fix the situation the quicklier the better.
With a happy and strong family you can talk about all, and now that you know much more about us, you can expose the convenience of wear a belt.
As you know, in my family mi mother wears a belt too, and It is perfect. But if it pass you will must be the holder, not your daughter (I can understand rage talked there) 
.
A bel can be a good tool to maintain a happy family, but you have to notice that this will increase a lot your responsibility about family.
Anyway, no matter the way, I hope you have a peaceful family as soon as possible.
I think same 100%
Ines A bel can be a good tool to maintain a happy family, but you have to notice that this will increase a lot your responsibility about family.
Only if it is fully accepted.
Angelina a belt does not currently solve the problems in the family. maybe later but not now
I can understand why a belt for her would be useful.But I agree too it is not the best thing to do right now,and never if she doesn't agree wilingly.

Vanessa Only if it is fully accepted.
You know It is only way in which I judge acceptable to wear a belt.
Forcing is not in my vocabulary 
Vanessa She seems not ready to agree to it,and not sure she would.But anyway,it is not the right time for starting it.
Again agree. It is what I tried to express in my first response. First is time for therapy, and love. Only in a peaceful home can a belt have a place.
