uncomfortable with idea of breastfeeding 😔

i really want to breastfeed / try to breastfeed but i'm having such a tough time mentally getting prepared for it - the idea of it makes me very uncomfortable and i'm so frustrated with myself - i know it's natural and so good for the baby but it's just such a sensitive part of the body and has been so sexual up until this point in my life... is anyone having a tough time switching over from "sexual" to "nurturing" in their minds? will it just happen when my baby is here? are there any tips or things i can do to help start to become comfortable with it? is anyone else struggling with the idea of it? thanks mamas 💕 i'm hoping once i give it a shot, i'll just know either way if i can do it or not...
