Torn about gender

Hey, thanks for dropping in.

So I've been stuck in a back and forth for a while regarding my gender. I am physically female, and personality wise quite feminine in the nurturing way, but at the same time, since I entered puberty I've felt kind of uncomfortable, especially with my breasts. I don't stand/sit up straight because I don't want them to show.

I like looking not feminine, I don't like having all these curves. Crossdressing is made very difficult by them. My favourite brah is the one that makes my breasts look flatter, but I am still too curvy to wear anything but a jumper or hoodie.
I can make myself up to look pretty and petit, and sometimes it makes me very happy. Most times however it just feels uncomfortable.

I want to have biological children someday, one of the biggest issues I have, and I don't much mind having a vagina. I quite enjoy being a female. Looking cute is pretty fun.

Can't help but feel like I would be happier if I wasn't. Or at least didn't have such pronounced features of one.
I prefer male or undefined pronouns, being called a woman makes me sad for some reason and I can't help but wonder.

I get a kick out of looking like a guy, being mistaken for one (before I speak anyway). It makes me happy to pretend. To walk with a wide gait to hide my hips, to wear big coats or jumpers to forget what I look like underneath.

What am I?
Can anybody relate and give me a hand on what to do?

Thanks for reading, sorry about the messy writing.

Hello nigel: There's not really much I can tell you about all of this. But I noticed no one had yet replied to your post. So I thought I would. I don't know if what you describe might possibly constitute being bi-gender. Hopefully other PC members will have more knowledgeable thoughts to share with you. In the meantime, however, I thought I would just mention (in case you're interested in exploring it) the website: bigender.net. Here's a link to it:

Perhaps it can be of some assistance with your efforts to gain clarification.
