You don't have to explicitly state you interest. I find it much more effective to simply escalate while you are qualifying and rewarding her. Good job at getting the kiss. You don't have to go into a heavy makeout to progress to sex. In fact, making out for too long can just give her validation and go against you. Set up time to see her and kiss at least once more before you pull her back to you place.
