>>911469women with large breasts often want to be seen as pretty or cute not constantly seen as sexy or provocative. in addition, many have back pain if they are too big.
on the other hand, women with small breasts often dislike being considered cute and almost childlike and want to be seen as sexy and mature. in addition, many may struggle to breastfeed if they are too small.
and then besides that, you have firmness/saggyness, nipple size, nipple color, which direction the nipples point in, how much space is between the breasts, etc.
many women are insecure and complain about their breasts for these reasons
