In a word, no mate. But if I were in your shoes I'd stick with your punting type for the punt and see if you can fuck your size 14-16 bird if and when the opportunity presents itself.
I don't know about you MS, but for me civvy sex and punting sex are quite separate (usually), so even if I punted a 'type' to see if it might work in civvy life, there's no guarantee the experience would be similar enough to make the comparison a valid one. And then all you've done is miss an opportunity with a firm-bodied hottie you wouldn't normally be able to see because they're too far away, and not really learned anything either.
And you kind of know what you're letting yourself in for already if you've seen a size 20+ WG. After that size 14 will seem skinny
