Q: My iPhone 5s won't let me choose my number for iMessage just emails show up in send and receive just emails not my number and I want to send and receive numbers with my actual phone number how do I do this

Could try to turn iMessage off on each device you've previously had registered, then turn it back on on the device in which phone number you want displayed first.

I've heard of some people having to reset network settings on the device first too.

Answers available in this article: iOS and OS X: Link your phone number and Apple ID for use with FaceTime and iMessage - Apple Support.  I "lost" my phone number in Messages on iPad and iMac after changing Apple ID password.  Long call to Apple support solved it, but the procedures are laid out in the above article.
