Hesitant to send nudes because of my smaller size - not getting any hookups because of that

Hey, so basically the title. In my opinion, I have a decent body, I try to keep in shape by going to the gym, I’m also tall which is always a plus for tops, but I’m on the smaller size. I have photos with me on Grindr and people usually show interest… until the “nudes?” question. I know it’s their right to know what they’re getting into. But I just feel overwhelmed, especially because it also looks way smaller in photos than in real life because i m a bit wider. So every time I try to take a photo of it, it just doesn’t look good. And it shatters me. Do you have any advice in regard to taking nudes or to how I should fix this situation? Thanks!
