Is it normal to not be sure if i want to be a guy or a girl..?

ok so i am a girl, but i am pansexual. meaning i can love anyone and it doesnt matter what their sexuality is or their gender identidy is. it's mostly based on their personality and who they are as a person. but sometimes i dress up completely in guy clothes and i like when people think i am a guy. but other times i like to look a little girlier and pretty. i like putting on make up and doing my hair and just things that girls do. and i have had thoughts about becoming a guy, and i like the idea of it. i love to just be one of the guys. sometimes i think i would fit in better if i was a guy. i like the idea of being the more "manly" part of a relationship and taking care of the other person. but i also like the idea of being with someone who is more "manly" and can take care of me..i like things from both perspectives and im not sure of what to do..help? much appreciated :]
