Chatting is like playing chess.
Your step, her step. Here you will not be able to attack the queen with all pawns at once. You need tactics and flexibility. The best weapon is ambiguity.
Say something about the topic, but also about the sexual content. These kinds of conversations and jokes get guys to bed much faster than trying to say everything directly.
Give hints, talk about opportunities to be together, and soon you will indeed find yourself with the girl on your bed.
