Is it wrong that I defended myself when my boyfriend called me selfish and childish?

My boyfriend and I differ on having kids. Most of the time, I feel like he's not being understanding enough towards the reasons I have to not have any kids, such as having body image issues and the fact that pregnancy causes huge changes in a woman's body. It's also the fact that kids demand an awful lot of ur time and attention, something I don't think I'm fully ready for. My boyfriend on the other hand, really wants them and tries to convince me by sending me photos and videos of babies, saying things like "I'll convince u to have kids don't worry". One day I told him that kids take up a lot of ur time and I wouldn't have time for myself, he called me "Selfish and childish" and said that when I'm 35 and I see my friends having kids I'll regret it. I told him that I'm not selfish and childish for having body image issues and caring about my body which will be fucked if I have a child and that'll be really unsettling for me given the severity of my issues. I just don't want to be a terrible mother and ruin the life of an innocent child. Am I wrong for defending myself in front of him?
