Im really freaky and enjoy sex, like all the time... but my gf is in to more "making love" then freaky stuff. I know she is freaky but how do I get her freaky side out?
Classic, Sallie - reminds me of a shot from show here
Character 1: "There's a girl out there I want and can't have."
Character 2: "You over-inflated her and she popped?"
You talk to her and slowly try new things with her. Respect her limits and take it slow. Just ask. Maybe she wants more kink too.
You can't make her more freaky. She either is or isn't. If you not going to be happy with what you have then move on because you will always be searching.
