Oh, also, you can look at it as Rogue wanting to do everything, but not knowing where to begin. After years of not being able to even hold hands, she's like a kid in a candy store and wants to hand the reins (figuratively and literally) to someone else. She trusts and cares about the player enough to make sure she'll enjoy herself. There's a lot that has to go unspoken, for obvious reasons, but while some of the quirks can be seen as having unhealthy aspects to them, they all stem from the characters being comfortable enough to say 'hey, this is what I want, can we try it', which can be very difficult to do, even in a stable, healthy relationship.
