So I'm confused about my gender identity and expression

So I'm a teenage cisgendered girl and I just very recently figured out my sexuality and since then I've been questioning a lot of things about my gender. Not my gender itself, I am a cisgendered female. So for a large part of my life I considered myself a tomboy, but as I get older I realize that I want to be a more masculine person, but still identify as female. I want to dress more masculine, or in "boys clothes", use "men's" shampoo, body wash, deoderant, etc., wear cologne, boxers instead of women's underwear, etc. I want to keep my hair long though and when it comes to binding, part of me wants to because I feel...bad(?) for lack of a better word when I look in the mirror and see anything but a flat chest. Don't get me wrong, I like a lot about myself. I'm fine with my face and most of my body but just something about my chest makes me feel almost sick, like a knot in my stomach. This feeling was around a lot when I was younger, but went away until recently. I identity as lesbian as well. I don't really know what to think or feel because I don't if this feeling will go away again. I don't know how to describe this really or what to tell people. How do I go about this?
