One for the Team

Alex dumped her and Jen's not sure why. Okay, he'd been her first, but she thought she'd done rather well, sexually speaking. Why did he all of a sudden tell her that it wasn't working out? What was wrong with her? Ken, Bart, Davey and Jason--her best friends--all try to convince her there's nothing wrong with her. In fact they seek to prove it to her... by first-hand example. That's all well and good until Jen starts freaking out. She's sleeping with her best friends. All of them. What's up with that?
