Legally speaking I would be giving my time to you in exchange for a fee and what happens during our time together is between us as consenting adults.
It's best to give me a quick ring before hand so we can have a chat and agree what's really important to you. Contacting me via e-mail is also a good way of us discussing your needs. Only go ahead with me if you're absolutely sure of everything, as I do not want you to be disappointed in any way (which I am sure you won't be!) as well last option you can book me tru my Contact page if you are outside of the UK...
