One thing that speaks to the possiblity of hormonal influences contributing to sore nipples is that many women nursing during a pregnancy find their nipples become quite sore. If it was just toughening up or learning to latch correctly, then why would it start hurting with the toddler who'd been nursing for many months pain-free? And those who tandem-nurse often have painful nipples for the first week or so post-partum... Also, I recall some speaker using a penile analogy for nipples, in that one wants these organs to remain exquisitely sensitive in order to do their jobs. Building a callous doesn't seem to work in that analogy.
