I have been thinking about these questions lately and I came to the following conclusions:
(1) Why do I punt:
I punt simply because I want to experience being with a much wider variety and number of women (nationality, ethnicity, age, height, build, looks) than would be possible if I were looking for an encounter via the traditional route of meeting someone and then dating etc.
(2) What do I get out of it:
I want to lie and tell you all that it makes me feel amazing! But I won't. It can feel great to have a punt with a beautiful girl - just for a moment. But, other than during the encounter itself, I don't actually think I get anything out of it, or even feel particularly good about it. Once I have finished the punt, I often even wonder whether I should have bothered, but for some reason I always go back to it. I don't know why.
Would be interested to read why you guys punt and what you get out of it?
