How do I make women open up to me in every aspect of the word?

I Know alot about the male mind.I hang with guys alot and my life is just more interesting with women. I would like to know everything about women what they talk about,know how they feel ,basically to understand the feminine mystique.I would like to be so comfortable with groups of women that they wouldnt mind me seeing them nude at all. You know how some gay guys see their lady friends naked but dont mind. I would like to have a level of connection and much more as a Straight man. Well I just had this thought. That I would have a gathering with women in my house relaxing, watching tv,etc and they would be just be naked(i am straight guy) and talking and revealing their secrets on what they like and feel not caring that I a young guy would be there because we would be so close to one another .And I kid you not this wouldnt be nothing ual at all(Unless one wanted to ).How do I get to that level of closeness with the lady pals that I know. Do I have to have an amazing personality or this isnt possible?
