@BCS Only lewd girls think like that, as if they're missing out on a potentially pleasurable experience for themselves, rather than directly deriving pleasure from their love at it's source.
Pure girls are happy knowing that their crush is thinking of them and treating them tenderly, even if it's not exactly in the way they desire to be treated.
That's not to say that a pure girl cannot be lewd, or that a lewd girl can't be pure. The distinction in these cases stems from their reaction to the events, and the perspective it portrays.
Though the two types can (and do frequently) seem to be interchangeable, it is highly advised to learn the difference. It could save your life, or your time reading.
Remember,
If she regrets the loss? It's best to toss.
If she treasures the moment? That's a good omen.
