I don't know how I'll feel when I'm actually feeding and I totally understand that at the level of society there is an uncomfortableness about breasts being used to feed babies when they are so sexually objectified. Which could cause some women and men to feel that breasts are more about sex than feeding babies. Which would make them feel uncomfortable about breastfeeding, particuarly older babies/toddlers.
But... my intellectual feeling about it (I realise that I may have a more instinctive response once I'm feeding) is that it doesn't need to be either or, its all about context.
example 1: Hands and Fingers. When in an intimate situation, hands and fingers can be extremely fun and erotic because touch is sensual but I also occassionally use my hands to wash dishes amongst other mundane activities and I fully intend to use them to hold and stroke my baby.
example 2: Lips and Mouth. Again, these sensual areas of the body can be enjoyed in a sexual way whilst kissing and playing with one's sexual partner. But they are also used in speaking and eating and I'll want to kiss my baby.
example 3: Vagina. Obviously can be enjoyed in penetrative sex, but also associated with periods, smear tests and giving birth.
So I definately think I agree with the multi-taskers though appreciate that maybe I'll also feel differently about it once I'm feeding. I suppose that if you begin to associate your breasts with feeding a baby then when your partner touches them sexually it might remind you of the unsexy touch of feeding babies, so might become a turn off.
I agree that a lot of the uncomfortableness about breastfeeding in society though is down to hangups with women's bodies in general and breasts in particular being sexually objectified. I can't imagine anyone taking offense to a baby/toddler bottlefeeding expressed human breastmilk as opposed to formula milk made from cow's milk or soya milk. Its not about what the baby is eating, its about a woman daring to use her breasts to feed. Likewise, the horror at a baby nursing for comfort on its mother's breasts, this is seen as a bad habit, by those who wouldn't think twice about giving a baby an artificial teat to suck for comfort.
There's two things. One is about breasts being seen as primarily sexual objects. The other about the lack of exposure to breastfeeding in society so women seeing breasts as something private and the idea of a baby nursing for comfort is seen as too much of an imposition on their personal space, autonomy and time? (I totally understand that a woman shouldn't feel that she 'has' to feed or nurse her baby with her breasts if it feels uncomfortable, but its working out as a society where that uncomfortableness comes from). Whereas giving a dummy is handy (she doesn't have to remain attached, so baby can sooth itself in the car and other situations where nursing is difficult/impossible) and there's less pressure because dad/gran/sibling can take care of the baby, its not all down to them?
