Advice On Taking Nudes...?

Okay so me and my man have been together for a really long time and he knows how hesitant I was about sending nudes at first and respected that. However, now I'm comfortable and I want to surprise him with one, but I don't know how to take one when my chest is flatter than a desk and boney looking. I also have a scar on my stomach and stretch marks on my booty that are an insecurity of mine. Any tips or advice? :(
