Breastfeeding arguments🥴

My SO and I were talking about breastfeeding (I’m only 6 weeks but I’m the type of person that I like to talk about things before it happens) and we both agree that it’s the best option. Well I went into hypotheticals and said “well I might not like it” and he said that if I’m producing milk, I should be feeding the baby, that it’s selfish of me not to just because I don’t like it. And I said that it can be stressful (from what I’ve heard) and he was asking me how and I basically had nothing to back up my point of view. Like I said, i hope I can do it, but there’s always a possibility that I genuinely won’t like it and I feel like there’s nothing wrong with that. I feel like the last thing I should feel is being called “selfish” while trying to get a handle on having a newborn. So any advice is very appreciated. I know everyone has their opinions and that’s why I’m not mad at him, I just need reasons to back up my side of it. I just don’t know if I’ll like it or not🤷🏽‍♀️
