^Oh, no, I wasn't making you out to be a 'sicko' (I'm long past stuff like that), I just find these kinds of sexual behaviour very fascinating in an eccentric way.
I mean, in the mid-90s, there was this English court case where there were these blokes who consentingly nailed each other's bollocks to planks, and they got prosecuted for GBH (Grievous Bodily Harm) or somesuch, yet they were all consenting. I remember finding it all very fascinating, what goes on in thought, what goes on in legality, what goes on morally, what goes on logically, all sorts.
Fascinating stuff!
