If you are new, unless you are certain that full service is not for you and massage is what you want, maybe try booking an escort who does massage as well. It'll probably be better than joy but not as good as a proper massage provider, however it leaves you the option to explore what your limits are.
There is one lass, I've never seen her but she seems to be mostly massage but does offer full service too. I can't remember her name off the top of my head but will post if it comes to me. Advertises on both AW and VS, I think in G4. Blonde lady, Eastern European, I think.
