My philosophy of shoes is not just an abstract theory about female sexual self-expression. It has very practical applications in life.
Say, for example, there is some sexual activity a guy wants to try and he's not sure his gal will go for it. He figures he'll just mention it in the middle of sex and maybe she'll agree. Mistake. Unlike your male when aroused, before she can agree, she will have to think about it. And thinking will take her out of the sexual moment. End of session.
Asking a woman out ot the blue to experiment sexually is kind of like a woman who wants to be closer to her mate asking him out of the blue to share his feelings. Suddenly he's wary, not a condition that encourages sharing. A woman would do better to suddenly sniff the air and say, "Honey, I smell gas."
Even if you have an electric stove, he will get up and investigate. When he returns he will be able to assure you that all is well. He will feel closer to you and his feelings will find expression.
Likewise, an indirect approach with a woman's shoe-ness as your point of reference will help you get what you want more easily than a frontal attack. Go to her closet. You will see amazing pairs of shoes in there that she has never worn. They are all aspects of her sexual person, just some are less confident and don't get to go out in public. Pick a pair of shoes that looks like what you want to try. Take them to Nordstroms or Saks and ask for the shopper lady. (Your upper-scale stores will have people whose job it is to help the shopping impaired.) Tell her you need a dress that goes with the shoes, price is no object.
Go home and slip the shoes back. Hand the dress in a wrapped box to your lady and say innocently, "I saw this and I thought of you."
When she opens the box, her first thought will be, "I wonder if I have the shoes for this dress." When she goes to her closet and finds the perfect match, she will feel understood to the depths of her soul.
Take her someplace that goes with the dress and shoes. When you come home, the dress will come off, but the shoes won't.
