Well we must say we do tend to look at who potential playmates have played with as we feel birds of a feather and all that. But having said that not all verifications mean they have actually done anything at all (I can think of 5 veris we have on another site that we have never had any sexual encounters with but have met them socially say at a club) Only reason we would bin someone on the grounds of previous meets is if either are not practicing safe sex then we run a mile.
