The first time a baby latches on is soooo excrutiating there can never be anything remotely pleasurable about it!
I've literally cried and I didn't even cry while giving birth!
I hated breastfeeding! Raw bleeding chapped nipples are not my idea of fun.
Not my idea of a turn on either.
(Who knows, maybe that's exactly why its so painful, to seperate the 2 acts psychologically for us women)
I guess your opinion is largely psychological, we don't look at our babies as sexual beings, also breasts were created for feeding not pleasure.
Just turns out someone figured out they CAN be used for both. IMO if we have to choose a function and not engage in both, then my vote goes to the breast's natural function of feeding, even though I didn't enjoy it.
Its good for baby, so I did and would put up with it for as long as required.
