You probably need to see a few girls first to get some punts under your belt before you attempt a 2-girl. Start with a short punt and look for a nice girl who's been recommended by fellow punters to get those newbie nerves out of the way.

Girls that I've met who are attractive, have good English and friendly, but not overwhelming personalities...
