Well, as much as I'm against turning POTCO in to eHarmony, I'll just give you little tip:
A girl shouldn't have to be in a relationship with you because she finds you as strong, or what you know how to do in game. You don't even need to involve any aspects of the game. Just, get to know her. Talking with her, about anything - whatever is on yours or hers mind (especially hers, ESPECIALLY hers.) In time, things will get to wrk out by itself. When there can be no physical relations, it really all matters on whats inside
