If you could pull a diamonds girl, I don't think you even need to resort to punting.
Three points anth:
1) northern82 might not be who he says he is, bit of a bullshitter perhaps. Not saying he is, just don't believe everything you read
2) prossies are not the hardest to pick up for girlfriends/fuck buddies/whatever. Who wants to date a prossie? Not many of us.
3) a lot of punters actually do this for the convenience of fucking randoms, no strings attached. It's just a lot easier than conventional dating, particularly if you're in a longterm relationship.
