Interesting article. I think the passage of writing described is intended to be provocative. There is a well-known confusion in society about breasts - hence the men who don't want their wives to breastfeed.
When I was breastfeeding, it did cross my mind (i.e. the thought that it could be deemed sexual) but it didn't 'feel' sexual. Different context, different hormones. If anything, I found the physical sensation 'irritating'. I often didn't want a baby (even my baby!) attached to my front but when a baby is crying for food, it is the lesser of the two evils. And I wanted to do what I saw as the right thing, to breastfeed.
But I definitely experienced the oxytocin effect. I didn't look forward to it but I calmed down once it had started into a feeling of relaxation and peace. I recognised that it was the best way to bond with her. I enjoyed the intimacy, feeling needed, feeling able to do something important for my child, especially when she fell asleep afterwards. That was a huge sense of satisfaction to give my child that comfort.
And yes it is lovely to cuddle their little bodies. Small, fresh, beautiful unjaded innocence, spontaneity, their wriggling flexibility, soft skin, giggles, to watch the way they move. A sensual experience, not sexual. It is the amazement that I feel that I have produced something so imperfectly perfect. That I am her mother. But part of it is akin to the feeling that I get about any baby animal - a kitten, a foal - the maternal feeling, the cute-ness, the big eyes, the grace of new life.
I remember seeing a documentary on tv about an experiment on monkeys separated from their mothers and left in bare cages. They reacted in the same way as the poor children left in those orphanages in Romania or Bulgaria - rocking, banging their head against the cage, failing to develop phycially as well as mentally, slowly going mad.
Maybe there are people who find the sensual experience sexually arousing but I think most people, men and women, instinctively know that it is something different - that physical bonding between parent and child, the cuddles and kisses, is one of the most important parts of the child's development. Nature makes it pleasurable/sensual for both parties to make sure it happens.
Probably gone a bit off topic here but...
