Forgetting the dubious nature of videoing a girl in your bed for a moment, why would you need to?!!
There are loads of videos on the web showing guys getting numbers from approaches, so watch them, see what the guys are doing well and then (and this is the most important part..) GO OUT ON THE STREET AND TALK TO GIRLS!!!!
So many guys seem to just want to see video after video, but in the long run it won't help you! By all means use a video as an inspiration to go out and do approaches yourself, but if all you do is watch DVD's of guys getting numbers, after a while your mind will subconciously start to say "Oooo, their good! There's no way you could do that; forget it loser!" because you have no personal frame of reference! Yes, you'll get blanked, ignored, flaked etc.. but that happens to all of us and more importantly, not only will you learn from those bad experiences, you need to experience them to improve!
Remember, the only thing that will get you girls is going out and approaching them!!
