Well she has been on AW for 18 months or so without any ratings.
There is very little on that profile to attract me so I am guessing its the £90 an hour that is attracting the OP.
But your right about wanting feedback and feeling the need to be safe.
I suspect she is a Ninja (don't ask....just a hunch) and will attack you as soon as you enter her lair. Beat the crap out of you and steal your watch, phone and wallet (Take not newbies....what not to take into a punt).
She will then wank you off into a condom even though your out for the count so you can't say she did'nt give you what you asked for.
Your word against hers.
These are just my thoughts mind you.
Other more wiser heads may disagree.
