I love repeat friends

It is fun to establish a rapport with said individuals - unfolding fantasy and releasing inhibitions is much easier with a familiar face. I would say the majority (upwards to 90%) of my dates are with repeat offenders; if I jive with someone, I want to insure their return. I think this is a great introduction into the "boyfriend rate" - multiple visits almost always come at a lower donation because I prefer to keep myself in good company. That being said, I know that I have been very blessed with the individuals I have met via hobbyland - most from this board.
So, to answer your question, I think if chemistry is present on an initial encounter the odds of a swift return are high. The mutual benefits of such are hard to ignore and sometimes difficult to replicate.
There. That is just my two pennies
