the question is how much do you want and love this girl?? enough to forsake the "freaky stuff"??
love is all about meeting each other half way, but if she's given it a fair try and she still feels uncomfortable with some of those things, then neither you nor she can change herself
and what's lovemaking, if both parties are not enjoying it, and having a blast together??
so if you really love her, then go after her, being ready and able to drop those "freaky" attitudes in bed, who knows "sex/lovemaking" methods/stuffs are getting uncountable by the minute, so maybe you guys would sooner or later come up with ones both parties are comfortable and happy with, till then you just have to stick to "the ordinary"

those are one of the sacrifices love drags along with it
but . . if you can and will not live without them "freak stuffs" then let her walk/be, you might be lucky enough to find someone who also shares your "freakingness" and enjoys the "freaky stuff"
you can't eat your cake and have it, you just have to choose one and live by the decision no matter what. so dear, what's it going to be??
