I don't think they had sex at all ---
Erin just had that huge fight with her roommate, and the friend most likely to let her crash on the couch in the event of a huge fight with said roommate, remember? So she goes to the bar, not sure what to do with the rest of her night. This guy shows up, offers her a drink, then rejects her direct advances. IT IS PERFECT. She gets drunk and starts a fight so she can have a place to sleep it off WITHOUT hooking up with random bar guy. Erin Stout, Victorious.
