 Some women lose the ability to be aroused while breastfeeding, and thus would not find lactation with a sexual partner to be erotic.This can be a result of physical reasons (soreness) or psychological reasons (conflicted about her breasts being used other than for an infant).Because female breasts and nipples are generally regarded as an important part of sexual activity in most cultures, it is not uncommon that couples may proceed from oral stimulation of the nipples to actual breastfeeding.
