This IS a very interesting topic. There are loads of threads on these boards where various means of controlling a slave or sub are criticised because they apparently show there is no trust in the d/s relationship.

These comments often make me think 'God, I am just terrible, because I CAN'T honestly say I would never ever masturbate without permission without a chastity belt on, or would always always do my tasks without threat of punishment' etc etc. So...it's nice to remember that many of us on here indulge in the bdsm world secretly behind our partners' back.

And no, that's not a dig at anyone, because I've been there myself.
