On that basis that you made an enquiry about the provision of sexual services at the massage parlour either:
(a) on the telephone during a conversation, or
(b) via a text message,
then you have not committed the offence of soliciting a person while you were in a
street or public place for the purpose of obtaining a sexual service as a prostitute (Section 19 of the Policing and Crime Act 2009 introduced section 51A into the Sexual Offences Act 2003):
51A Soliciting
(1) It is an offence for a person in a street or public place to solicit another (B) for the purpose of obtaining B's sexual services as a prostitute.
(2) The reference to a person in a street or public place includes a person in a vehicle in a street or public place.
(3) A person guilty of an offence under this section is liable on summary conviction to a fine not exceeding level 3 on the standard scale.
(4) In this section “street” has the meaning given by section 1(4) of the Street Offences Act 1959.”
If you were in another country at the time, again, it would have been impossible as there was no solicitation while you were in a
street or public place.
The offence of soliciting described above was created essentially to combat the problem of 'kerb crawling' (and creepy old guys pestering women in parks etc.)
Basically, the pimp is talking complete and utter bollocks.
