Exactly, embrace those things about yourself and dont be afraid to express it to her. If I were talking to a girl about wanting to experiment with different fetishes, the best time would be to bring it up during Foreplay or when things are about to get hot and heavy.
Be serious and dont treat as a joke or laugh it off if she refuses. Tell her straight faced what you'd like to try with her. If she doesn't feel comfortable, not a problem. Things that she likes you to do when you have sex with her? Use as leverage
Thats the push-pull of this whole thing. Dont be hurtful or mean about it but be playful about it and dont let her have too much fun.Why does she get all of the fun?
Dont be afraid to go balls in with this, it's respectable as hell. Alot of people keep it bottled up inside because their insecure about their own sexual fantasies and they just become frustrated.
