Grooming

I've been deep in thought the last few days. What constitutes "deep in thought"? I don't know. I'm normally not a deep person. The deepest I get is when I go swimming. (It a joke; get it?) Back on track . . . I've been deep in thought about a sort of grooming that occurs. I don't refer to personal grooming; more of a social/relational grooming.
My stepsister has suggested to me in the past that if I intend to enter marriage one day; I have to succumb to the female gender's social grooming. "What do you mean?" I queried. She told me that women look for a guy who is willing to adapt to her sense of nature. For instance, a girl is looking for a guy that she can play dress up with, is willing to take interests in what she has interests in, and is willing to subject himself to emotional movies. I've conducted a small study among my friends both married and dating. The results seem conclusive to the hypothesis. (I won't mention the names of the subjects.)
To sum it all up: If I am to enter marriage or any sort of romantic relationship, I have a few things to change about myself. I have to dress so bad that women feel a need to dress me up. I also have to take interests that girls have (e.g. shopping and make-up). I also have to start exposing myself to the genre so commonly referred to as "Chickimus flickimas". According to my stepsister’s advice that should give me all I need right?
