I think we go through stages at different times of our punting lives: We don't simply fit into category A, B, or C and stay there forever. I started out as a d). I was a late developer physically so teenage sex and girlfriends largely passed me by. When I discovered I could pay for it, I simply stopped worrying about my lack of success and did that.
When I did finally develop and catch up with my age group, I was very successful with girls in my late teens and early 20s but the die was cast and while in those years my punting reduced and a succession of girlfriends became more prominent, I never stopped punting completely. I'd learned to like the variety and excitement. I also didn't see punting in the context of relationships; paid sex was in no way a reflection of my feelings for or commitment to a proper girlfriend. It was like going to football; just a form of entertainment.
In my married years, the degree to which I punted tended to be somewhat related to the degree of marital sex I experienced. As the former diminished and then more or less stopped, the latter increased. Punting was a lifeline in some ways. Affairs (I tried one but it was far too much like hard work and I ended it almost as soon as it began) held little appeal.
Now, single again and in middle age, I punt through choice. If I happened to meet the right woman and things worked out I daresay I'd go for it and my punting would reduce (but not stop) again. However, after a couple of bad relationships since the end of my marriage and finally having learned to enjoy my own company (a lesson that renders the bad relationships almost worth having gone through), I feel less and less need to even look beyond paid sex. Living on my own, doing what I want, and engaging a WG when I feel the need for sex works just fine. I'd accept more, but I'm not desperate enough to want to look for it.
