I'm not a competitive guy in all aspects of my life, but I get what you mean about sports and cars. I like fast cars, but I don't really care about how strong it is or otherwise. Sports? I tried really hard and, while it's fun as a social gathering or event, you won't find me vegging infront of a TV watching football or basketball all evening.
With that said, there are strong masculine aspects of my life that I still value, like sex, being attracted to another woman, etc. However, that doesn't mean that I view my situation as fetishistic. I like being both and the freedom of proper expression it allows me to get away with. I like being pampered and respected as a woman, but I also like gadgets, widgets, building computers, talking about women, etc. I've learned to appreciate how being both fits in my life.
