It is incomprehensible to me that the subject should be banned. It is of very considerable interest to men and to ladies, and it's worthy of discussion. Lots of people are uncertain about the use of these things, and the more information that can be shared the better; it seems entirely appropriate as a topic for an adult site such as this.
I have read through the thread referred to above. It was finally locked by Dawnie, who quoted her own earlier comment "If we can all be sensible about it then the subject is open to discussion".
If this is so, then the constraints on mentioning the actual 'word' seem bizarre.
