I don't know those messurements LOL but I really don't think it matters. There is someone for everyone. Big small what ever! That's part of swing it's the different spices that make it nice! But I can say your insacurities can really make it a bust. Confidence is a good thing. People look for personality and looks. If you don't have the first no one usually cares about the second
good luck and relaxe it's supposed to be fun and free
