am I in the wrong?

hello, I'm a newbie with BDSM and I wanted to start exploring more so I've been talking to this Dom. It's been a few months and basically all we did was sexting and spicy photos (no nudes since I'm not comfortable with that). Yesterday I was pretty drunk and I texted him, we ended up sexting and exchanging photos, in the heat of the moment I said something along the lines of "do what you want to me". He interpreted that line to mean that he could ask for more in the photos I've been sending but when I sobered up I was hesitant and I got mad when he asked that. He was asking me what I was comfortable with sending and I told him "no more than what you already saw", he said that he expected a reply like this and that I basically used him on the false pretence that I would send more explicit photos. I don't think that's what happened, I was drunk and he knew my limits so I really don't know why he was expecting me to go outside them, to that he said that boundaries can change. We were both upset, we sorted it out but I wanted an outside perspective.
