First of all, those videos are delusional. They are selling simplification of reality where "they" (being women in this case) are the bad ones while you (men) are the good ones. Complete waste of your time.

Besides if you were to date a cheater, she would find a way to cheat regardless of your effort. Opportunity does not create cheaters, it only enables them. Conversely if she faithful, she will be so without your supervision as well.

Addressing alcohol issue. Yes getting dead drunk in bars/clubs can lead to many bad things, and cheating is far from the top of the list. However, it depends where would they go to, it's not every place is some pit full of predators. Not to mention they will be together in all girls group.
