Oh, believe me. I want to help.
Its a matter of being safe on all ends though.
I'll say this much:
You'd be surprised how many girls will do this for you. You'd be surprised at how easy it is to set things up. You just have to use your head and practice angles.
Also, if you're gonna use a bag setup, make sure to buy duplicate bags. One to use and one as a decoy. That way, if the day comes you see a video and think people are getting suspicious, you can swap the decoy in and sacrifice some time. Let the decoy get "caught". I guarantee you, if the decoy gets "caught" once, you'll not have to worry for awhile. One rule though: when swapping a decoy, pretend you're still "on" and act the same way.
