support this hobby. Some of these girls will run you some good chunk of change. I provided you a Newbie thread, hopefully you spent some time finding some decent threads there.
If you are uncomfortable with giving you SSN, then don't. Some guys here don't. When I book a provider, I don't give out my work information or SSN. They only thing I give them is the datecheck, preferred411, provider reference, TER handle, and a name I go by (not my real name).
