Need some help with a Teen Titans lemon

[cboy]

I'm working on a TT lemon that has a romance between my character and Jinx and I'm trying to find something to lead up to the first lemon. In the story, my character notices Jinx is attracted to him, but he considers her a slut and will not screw her, even though he himself is also attracted to her. I've started the first lemon, but I need a way to lead up to it. What should I have Jinx say and/or do to change my character's mind about her?

Also, what are some good ways to hint at an abusive childhood?
