Welcome, Soraya. I can relate with how you're feeling. I'm a 23-year-old female, and I didn't start majorly questioning my gender until 3 or 4 years ago. I too desire to be male physically, even though sometimes I still express myself femininely (e.g. makeup, dresses).
Because I actually like labels, I identify with the terms transmasculine and genderqueer. But don't feel like you have to label what you're feeling unless you want to. Even within a "category," there are as many experiences as there are people. But, you can definitely find people here at Susan's with whom you have things in common.
Like Elis said, take it at your own pace and experiment with whatever you find comfortable. If you're concerned about the investment, looking into buying clothes from a thrift shop or using items you already have; for example, I started out binding with sports bras and packing with a balled up pair of socks.
Above all, trust yourself and don't be afraid to embrace whoever you find yourself to be.
