How do you feel about recycled nudes?

I sent my girlfriend nudes early on in our relationship. Not too long ago I was showing her my Snapchat memories and some of them were me dancing (twerking). Seeing that made her curious to ask about nudes I’ve sent her and if I ever sent them to anyone else. I was truthful and told her the nudes were old. I don’t really take nudes anymore so yes someone else had seen it. I’m not as confident as I once used to be in my body and I don’t feel comfortable taking them nor do I feel like going through the hassle of getting angles right etc. She was upset then but it’s been weeks since we had that convo and she’s still upset. How would you feel about this? And how do you think I should go about this?

Context: she has never sent me nudes. She’s a touch me not & not comfortable showing her body.
