I've tried, but I still can't relate to those who are so pissed with the whole Josy/Maya turn of events. I mean, seriously.
If you pursued Maya, you did so knowing she did not want guys hitting on her. She outright told you it was best if you weren't attracted to her. She admitted she had been with only girls. And despite her inner struggles, she still thinks you're such a great guy that she's willing to switch-hit, even though she has known you for barely a week, which is so weird because that's exactly how long you have known her.
If you tried to avoid Maya, you were forced into a couple of sex acts with her anyway. Poor you (She's so hideous, right? Tell me you skipped through those scenes because you weren't interested). And if you did try to avoid her, you weren't emotionally invested anyway.
Josy also had her inner struggles, and you knew this from the start when she admitted she had a crush on you. If you slept with her, you did so knowing she was in a relationship. If you didn't, you're all torn up because a girl you've been on two dates with and didn't get past 1st base turns out to be a lesbian who's willing to switch sides for you.
As far as infidelity goes, neither of them were sure they were still in a relationship until a little while after Josy knocked on the door.
And if two girls in real life, who looked like Josy and Maya, wanted to climb into bed with you at the same time when you're a young, single college student, and you turned them down, all I can say to that is WHAT THE FUCK IS THE MATTER WITH YOU?!?!?!?
