I wonder if the 'age of consent' for consensual spanking is to do with pornography as you cannot legally buy porn under the age of 18 or see a film that is an 18 ( used to be X rated and it was used as a selling point.) Also when I have got to any fetish fair with Himself you had to be over 18 to enter the premises where the fetish fair is being held. Leading on from that it makes kinda sense for the fetish fairs to be held in nightclubs/ gay nightclubs so the general population are used to it being an over 18 thing and not out of the ordinary plus i suspect finding a venue that will let you hold a fetish fair might be potentially difficult - i don't know as i have never tried to organise one.
Strictly speaking - with my limited understanding of the law in England and Wales - you cannot consent to any act if it is actually assault - this i checked on cps.gov.UK
Assault occasioning Actual Bodily Harm
Offences against the Person [1861] section 47"The offence is committed when a person intentionally or recklessly assaults another"…"An

I had a vague idea about this as I am the daughter of a career copper and used to help him study and I also used to update his full set of rules and regs and law changes etc when necessary and I won't get into what a total nightmare inserting the relevant pages for
Police And Criminal Evidence Act [1984] was!
That's my twopenth and now I will go and crawl back under my rock and do some work.
