At two weeks old, this relationship is too young for sex - and you should know this! Bring flowers instead and expect a hug or kissing, but not sex. Secondly, fisting is not foreplay, it is a very delicate and incredibly intense and dangerous act when making love. You need to take this relationship slower - have you even thought of your date's attitude to sex? Have you considered that she might not want sex? Slow down, and let her tell you what she wants to do with you. Foreplay is a mutual thing, and if your date isn't ready for intimacy, don't pressure her.
