For me it was when I was 20, back in 1993. I'd been on the pull up Norwich with no luck, and one of my mates suggested for a laugh we go down Rouen Rd and take a look at the WG's. Three of us walked down there and were amazed, firstly how many girls were there (around 25-30) and secondly how fit over half of them were. Our trouble was that with 3 of us together walking around some girls soon walked off, but 30 minutes later the 3 of us were in a flat with 2 WG's (Lisa and Jane), both blonde stunners. I had to wait while the other two were having fun, but that meant I had a choice, I choose Jane and £20 later I'd spent the best 30 minutes watching her play with herself, and have a good bj plus sex.
On the way home, the 3 of us decided this was the way forward, it was simple enough, albeit a little bit nervy while talking to them, plus it was reasonably cheap and it saved hours of trying to pull some bird in a club, buying drinks to get a snog and a feel if lucky.
20 years on, and we still all punt, with it taking us to Amsterdam, and all over the UK, most recently going up to Manchester for 5 days and having some fantastic punts.
I think having mates who also do this, makes it a better experience, being able to talk about the good and bad about the punts we have. Manchester was one of the best weeks ever, so many punts and great laugh with mates over a few beers talking about it.
