Thanks everyone for your replies π
I was just talking to my husband about this this morning. in principle, he has nothing against it. He also thinks we should support their wish.
later we had a long talk with our daughter. or rather two conversations. meanwhile my husband and I talked alone again.
we wanted to know how she imagines it and how she thinks it will be.
basically she would like to wear a belt like that for serious use, no kink use (she knows, i wear them for serious and kink use) as she speaks, her goals are no sexual activities without serious releationship.
We think we'll let her try wearing a chastity belt. But I don't have an old belt anymore, so she can try mine later if she wants. it won't fit 100%, but with small adjustments it should fit very well.
she is still out, but she knows that she can try the belt later.
I also think that I will tell her about the forum here, maybe she would also like to comment on the topic here.
