Is it too early to be asked for nudes?

So we've been going out for a month now but have been friends for a couple months. He just asked me for photos but he kinda put it in a way where he was hesitating to ask and when he did he said he didn't wanna make me uncomfortable. I didn't send and won't send because that's not something I'm comfortable with, but i just wanted to get your opinion on whether you think it's too early and whether I'm being used in a way. I mean he's really sweet and loving even without the photos and even before we got together he was being sweet and all but i don't know.
