Michael What do you mean exactly? What does define to be a good keyholder in general or what aspects do you mean that are relevant especially for me?
What @Angelina and @Max9 answered,and I would add talk often with you,if you need to,and try to understand how it feels for you,physically and emotionally.
Angelina
Sure.
Michael
I'm not sure too,but,anyway,it means it can damage the penis.
A chastity cage.
Michael The other way around, that a keyholder might open the belt too often because he/she is too easily talked into opening it, might be a problem.
You should talk about it before,or after it happened once,to be sure she understand,that,even if you try a lot to make her open it sooner than planed/supposed to,she should not accept.It can be hard for her,but I think she could manage it.
Michael The second case is my case. It is my wish to be locked into a belt but that does not exclude some weak moments when I ask for the key. If I asked someone to hold the keys it is more likely that she would then give in and unlock me. Later I might regret this. Therefore for me it is a problem when the keyholder is not strict enough.
For it,talking is the key(😉).
Michael Expecting from a keyholder to always distinguish between real problems or pseudo problems (being too horny, lack of control at the moment) is not easy for everyone and can be stressful.
It would need some time,but she would probably finally be able to recognize it.
Angelina and I keep saying that it is almost impossible to end a fluent discussion
But it can be done in the appropriate topic,maybe with a link to it,and copying our last answer in it.
Michael How can I convince her, that right now I want her to refuse to unlock me no matter what reason I might bring up
even if I then might say that it wasn't meant that way or that I have changed my mind about this kind of enforcement?
What arguments would you use to convice her to adopt a role of a strict keyholder?
You should tell her she should not unlock you when you ask her,no matter what you say,except a "safeword" which mean she should take it off immediately.But,if you use it without a good reason,it should mean she would not accept to be your keyholder anymore,to make you avoid using it only because you want to be free with no good reasons.
Michael I hope it is ok that I continue this discussion or should a create a new topic for how to approach a gf as a keyholder with regard to the possible problems that I have mentioned earlier?
Better to create a new topic,or post in a related one.
Saintprudence
Good example.
