You can 'Google' the phone number for acouple of similar adverts but they don't give any further information.
The advert contains the usual caveat; This is not a sexual service :-)
Depending on what you're hoping for, the advert has been running for more than nine months and if more was on offer I would have expected there to be something on here.
So unless something turns up it will be up to you to TOFTT.
