I figured between a remotely average GF sex life and about 6 years of punting, the number has to be around 30+. Maybe a few more, but who's really counting once you get up there. I also don't do the math, considering that most of my punting happens in Japan and the cost ranges from USD $300 to $800, it's ugly if you start adding that up.
Of course if I lived in HK I don't think I would have saved more money, I would probably just have a higher count
