I don't know. The thing is, I did do a lot more "masculine" things pre-transition, but it's not like I'm actively repressing anything, not doing those things anymore because somehow I say to myself "girls don't do that." I actually feel like my interests have changed. There's a lot of things that I was REALLY into as a guy, like roller coasters, engineering shows, car racing, sports, card games, pretty much just things that are more mechanical and emotionless, where now my attitude toward them is just "meh." There's even times where I actively try doing the same things, but I just lose interest in them now. They don't really appeal to me anymore.
So sometimes I wonder if I was only obsessing about those things in the first place because I was trying to fit in as a guy better. And actually, you know what? Frankly I just do NOT obsess about things anymore. Ever. Something about having male hormones in me made me very obsessive. I'd constantly be going on "kicks" where I'd go from obsessing about roller coasters, to obsessing about gender issues, to obsessing about writing, to obsessing about anime, to obsessing about music, to obsessing about Magic: the Gathering, to obsessing about poker, to obsessing about Christianity. It was always an obsession, always something that dominated my thoughts and made it hard to think about anything else. Now I really don't obsess over anything. I frankly just feel like I'm going through life, doing what makes me happy at any given moment, and I'm in control of what I'm interested in rather than what I'm interested in being in control of me.
So I don't know. A lot of stuff that I was into as a guy I was possibly only really into because it was an obsession. And now that I don't really obsess about things anymore, it's just kind of lost its appeal to me. I don't really understand why this has happened, but it has. Frankly now what I'm interested in is having fun with my friends, whatever that activity may be. And most of the time when I'm by myself, I'm bored, and don't know what to do because I don't really have things to obsess about anymore. I still play video games, but I can take them or leave them. I still watch anime, but I can take it or leave it. I still watch sports, but I can take it or leave it. I enjoy shopping and feminine things, but I can take them or leave them. Etc.
So I don't know. Is that "sacrificing?" It's not like I'm actively avoiding anything just because it's stereotypically-male.
The only time I wish I could do something more masculine is in regards to clothing. I wish I could just go out in a unisex t-shirt or sweatshirt and not have to care so damned much about my appearance. But that's just because I'm still getting gendered male when I do it. If I could do it and still be gendered female, I guarantee you I'd be doing it. I only avoid it because the pain of not passing is worse than the annoyance of being limited to fitted shirts with feminine necklines.
