cant get my head around the definition of sexual service anyway. the ads will have to be very generic methinks

one of the clauses specifically exempts the girls from the threat of aiding and abetting but they would be witnesses to the prosecution of the 'criminal' client although admission immediately with a summary fine seems the likely way forward

trying to defend it - might work but messy depends on how public you want it.

'“Sexual”
4. For the purposes of this Order, except Article 75 (sexual activity in a public lavatory), penetration, touching or any other activity is sexual if a reasonable person would consider that—
(a)whatever its circumstances or any person's purpose in relation to it, it is because of its nature sexual, or
(b)because of its nature it may be sexual and because of its circumstances or the purpose of any person in relation to it (or both), it is sexual.'
