Snidi, you sound to me like you're at the very first steps of a long gender identity exploration. First, there is no law, rule, or requirement that says you must transition if you're gender fluid. Only you can decide for yourself what is right for you. What you need to figure out though is what is truly right for you. You're here which means that you identity is probably causing you at least some degree of discomfort or confusion.
Your attachment to your male identity may be 100% legitimate. In which case dabbling in cross dressing or mixed presentation may be enough to satisfy the desires you're identifying. However, as you start experimenting and exploring, you may find that much of the attachment you feel to your male identity is just the result of years of repression and social conditioning.
This is where I'm at right now. I'm still peeling back the onion, stripping off layer after layer of conditioned responses and values. I've found many of the things I was most proud of as a male I was only proud of because society taught me they were what I needed to do, be, or accomplish. That doesn't mean it was all for nothing. I have also discovered a great deal of real pride in many of the things I've been able to achieve in my life.
It's scary no doubt. A little over a year ago I considered myself nothing more than a man with a fetish for crossdressing. As I've gained knowledge and begun to strip away the denial, I've come to identify myself as genderfluid. But I do have much anxiety that as I continue to undo what society expected me to be and to become what I was truly mean to be, I recognize I may shift further and find that I am truly transsexual and in need of total transition.
At the end of the day, while it's scary, I know now it's a journey I must follow through on. It's going to be thrust upon me at some point in my life and I'd rather take it head on, on my terms, while I still have some youth left in me than wait until I'm a senior citizen and realize I've squandered most of my life not being true to who I really am. The biggest step for me to get started was and still is self acceptance. I had to break down a lot of my own internalized trans-phobia and love myself. From there I can work on being my truest me.
I don't know if that helps at all, but I do wish you the best of luck in your journey.
