"Robby didn't want to have sex with her until she was older, but Emily threatened to lose her virginity to a social degenerate who obviously went to school with her. Therefore, Robby agreed to make love to her. He didn't want her getting involved with a druggie."
I honestly think If an 18+ year old girlfriend didn't want to have sex with her 18+ year old boyfriend (whom also had a bad, abusive childhood), but he threatened to have sex with another woman if his 18+ year old girlfriend didn't have sex with him, people, especially radical-feminists, would accuse him of being a coercive rapist.
So, if anything, Robby is a victim, too! Emily coerced him into sex!
Interesting point.
