My husband family feel uncomfortable about me breastfeeding?

none of my hubbys family have been breastfed and infact the whole family are really against it. my husband included, when i told him i planned on breastfeeding he just went "like hell you are". he says he finds it repulsing and the thought of a baby sucking on my breast just makes him feel ill, he says they are used for sexual things and it just feels strange, his family agree, he also says that when baby gets teeth it is bad for them and it also makes it harder for them to self sooth. this just makes me sad would you not breastfeed to please people or just tell them to bugger off
