I don't think it's possible to make yourself trans. I think it's one of those things that you either are, or you aren't. No person who enjoys being their biological gender would even think twice about the concept, outside of trying to understand one of us.
What I do see when I go on line and read up on it and watch youtube videos and everything isn't an obsession so much as it is a realization and joy in the thought that I am not alone, and that there are other people out there like me who have gone through or are going through the same thing as me.
Living way out in the country in a small close minded town in Kansas makes me feel very isolated and lonely even with my wife (who doesn't yet know I'm trans, but I'm working with a therapist to tell her). It's hard for me to think of myself even as sane due to the people Im surrounded by and knowing what they would think and say if they found out.
Reading about others like me, talking to others like me, watching videos about others like me and so on is helping me to become more comfortable with myself one day at a time. It also makes me think more about it as I accept myself as a normal human being with my own unique thoughts, needs, and wants, who also happens to be transgender, artistic, a parent,
and a fan of Star Wars

I think about it a lot, especially over the last three years, which is why I've started seeing a therapist. But I feel it's not only something I think about more and more . . . but it's something I
need to think about more and more as time goes on. There's a lot to think about. Everything from doubts that last for 5 or 10 minutes for me where I ask myself if I'm sure I'm right about this, to worrying about how my family will react, to worrying about future employment, to what color nail polish I want, to losing weight, to what procedures I may or may not want for a number of reasons for and against,
and more. I think, especially while transitioning, you need to think about the full ramifications. And because there's a lot to think about, it really shouldn't be a surprise to any of us who are trans that we almost feel compelled to do so during an age of information.
So . . . I'm ok with thinking about it 90% of the time. I think about it while I'm playing video games, watching TV, making love, shopping, driving in the car, in therapy . . .
all the time. And I think I'd be stupid
not to do so, as I have a lot to think about and a lot to consider.
Now I have to work up the nerve to do something about it. Tell my wife. start experimenting with make up again. Shave my legs. lose weight (making progress... But some days I want to scream when I see ice cream or cookies or . . . and now I'm hungry!) work on my voice. Walk into the LGBT center at the college and start trying to meet people like me. Being patient (... Even if my wife accepts me, there's no way we can afford me to start even HRT until I'm out of college and have a job...). I need to start taking steps even if they're baby steps.
But back to the topic!
...I don't think it's unusual for those of us transitioning to think about it often at all. Not to sound too harsh, but I think we'd be being incredibly stupid and naïve not to.
