I think you are right, Jaz.
However, I don't see anything wrong in having sexual associations with women's breasts - Afterall, some derive great pleasure from their usually gentle but firm manipulation by aroused men.
Those Boob Beanies really slap the subject of breast-feeding in public in your face, IMO - You can't miss it and not look. Perhaps that's what breast-feeding mums want but I doubt it.
