In reading your post, I am reminded that not everyone knows that gender is not merely binary, but a spectrum. There are masculine women who are comfortable with being women. There are feminine men who are comfortable with that, too... and there are the people that truly feel they are in the wrong gender, and know it so strongly that they will do anything, including altering their bodies with hormones and surgery, to align properly with who they know they are. There are even people who have no gender, and do not desire a gender... or who express male and female either simultaneously or at different times.
I am transgendered, meaning I really do not match the genitals assigned to me at birth (and I sure as hell don't match the hormones in my veins), but I used to believe I could be OK with the body I had, if only I tried hard enough, and even strongly advocated that position. I know now that I was deceiving myself into taking an "easier" path, denying who I truly was and denying myself the possibility of who I might become.
So... if you don't want advice, please skip to the end of this post...

I recommend you research... spend time on these forums, ask questions, continue to explore... you may be in the early stages of a truly transformative experience, or you may be merely learning more about the world and yourself. No harm in either of those!
Then, if you feel like you are questioning your gender identity, please find a therapist who specializes in gender-based therapy. They will work with you to help you understand *you* better... and help you be the person you want to be, no matter what gender that is.
And please do not let your body get in the way should you determine that you need to transition. One of my favorite female friends is 5'10" and about 350 lbs... she is transgendered, and does not look very feminine at all in the stereotypical fashion (having to shave her face three times a day does not help, and she can't afford laser or electrolysis) but she presents female and, amazingly, *passes* on a daily basis, and is very happy in herself.

No matter what you chose, you are at least open and questioning... you will learn amazing things about yourself and the world around you. Much luck on your journey!
