I've always been the guy that provides something for the girls, like helping them with projects or assignments and such. And the worst part is that this is the only way I can interact with girls.

I know it's no good to be a pussy like I'm right now, I don't get anything in return other than being thanked or a bunch of smiling emojis :/

How do I connect and keep communicating with girls without providing them something? I mean don't you need a context (a reason) for communication?

I'm constantly improving my SMV, but even if I have the highest SMV in a room, how do I communicate with a girl in a way that shows sexual interest?
