Personally, I would never do BB. Providing a BB thread is not bollocks, I don't mind it. It is something some people do (I can't possibly imagine why, unless they have a death wish) but I don't understand.
But I do, actually enjoy reading HP's reviews.
HP - I do actually want to take the opportunity to ask you about it (and I do not mean it in a facetious way at all, it is a genuine question) because I do not know any other BBs. Given the known risks with BB'ing, at what point were you able to decide that a shag is worth those (possibly ultimate) risks?
