Laura it's only an assumption by my side (I haven't asked them their opinion on this fourm, nor will I ever ask them)
I think they wouldn't be too keen because they are too conservative with regards to everything that's "sexuality" related. (I currently am unable to think of a proper/better word) I think they would associate this fourm with something that is "weird/taboo" in nature.
Also at the house, we don't discuss about chastity belts in open, it's something that's discussed very discretely and privately, so I don't think my parents would approve of me describing my experiences in a public fourm.
Ps: I'm not proud of the words I use in this response, I'll come back to edit this some time else.
