These are very good points on the issue of breastfeeding. It is extremely difficult and painful for some women to breastfeed and for some, it is just outside the cultural norm. While breastmilk is the best, natural source of nutrition for infants because of natural antibodies, etc., bottlefed babies can be just as healthy. And you can still impart a sense of love, well-being, and comfort to a child by holding them when they feed.
I don't agree with La Leches stance that all children have to be breastfed. Just not true, and there are many of us running around now that were not breastfed and/or didn't breastfeed our children. However, I do believe La Leche does have some very good information, much of it on their website now, for explaining how breastfeeding works and answering questions for young, pregnant women that may want to try breastfeeding.
Having said all that, the way I understand the breastfeeding/"sexual" connection is that the nipple stimulation stimulates the uterus, causing it to contract. These contractions help the uterus return to it's pre-pregnancy shape. Its all biology and one of the ways our body continues to help itself "heal" after the birth of a baby. Somewhat like the normal contractions a female feels when she hits the big O, which is where the "sexual" part comes in. It is not like when you are "lusting" after someone. It's not that kind of "sexual." It probably wouldn't even be thought of as sexual, except that the contractions are similar to, well you know...... I was also under the impression that the feeling went away after the uterus returned to normal size.
Several years ago, CPS took a woman's child away in the small town I lived in, because the woman contacted the public health department regarding these "feelings." It was her first child and she really wanted to breast feed. It was a bit of a battle for her to get the child back, which was very sad, because she was a good mom, and the baby was only a couple of months old. She did enlist the help of the La Leche League and that is how it was all explained to me. She was my friend.
