Is it normal that i like my wife to go with other men for me.

Every Friday night I help my wife to get ready to go out with her friends. I choose her underwear specifically sexy or erotic knickers, knowing she will probably be having sex with a male friend.
As soon as she has left I get changed into a baby doll nightie and matching knickers and watch TV whilst waiting for her to return. I am on edge all evening wondering what she is getting up to, this keeps me excited all night. When she comes home normally between 11pm and midnight, we go up to our bedroom and she puts lipstick and purfume on me. I then remove my panties, and remove her panties and put them on, I can feel they are damp and sometimes very wet. When I have her panties on I begin to perform oral sex on her whilst she is telling me about her exploits for the evening. She nearly always comments on how big and manly her friends are compared to me. All this time I continue to perform oral sex on her licking and tasting the results of her and her partners enjoyment. The taste and humiliation I get when she is telling me I am just a small sissy who should enjoy the taste of a real man turns me on incredibly. When she has reached what she considers an acceptable orgasm and is nice and clean, I am instructed to play with myself and soil the knickers I am wearing.This makes me extremely excited and I am satisfied and exhausted when I am finished we normally both sleep well.
I know this sounds very kinky but I love the humiliation and sense of vulnerability I feel. I also enjoy wearing the female lingerie. My wife loves her freedom is this really so wrong?
