I've had 10 punts so far this year - 3 of them with the same WG, who I'd not seen before this year but who's quickly become a "Regular".
Looking back on the those 10; I'd say those 3, and 2 others, with WGs I already saw regularly, but not often, were above average. [But then, have I said they were above-average because I was seeing a WG whom I knew and with whom I felt relaxed and comfortable?]
As were two others, with WGs I'd not seen before but will definitely see in future.
That leaves three others:
2 were "Ok; but I can't see me going back any time soon."; and
1 where I didn't enjoy the experience, which was so poor - she seemed to be p1ssed [at lunchtime?!] - that I started a thread on here, asking how can someone who doesn't drive find an equivalent excuse to "I've left my wallet in the car"! Yet, despite that, she got me to cum, which [because of my age and my dependence on Viagra] doesn't happen as often as I'd like it to.
So, by some reckoning, I've had 5 well-above-average punts; 2 above-average; 2 "OK-ish"; and 1 where I was looking for a way out within 10 minutes of an hour-long appointment.
However, that last WG got me to cum, so that's a Positive punt and, by some standards, perhaps ought to be rated above the two I've shown as "OK-ish". It just didn't feel like it at the time. Perhaps it's to do, as Silver Birch hints, with "clicking" with the WG. I suspect that's a phrase that will be anathema to some punters on here; but it may be a case of, and [believe me!] I wish I could think of a better phrase, "horses for courses".
