My partner got to JJ when she was pregnant with our daughter - she's not a fat woman, she's just got disproportionately large breasts. She had real difficulty getting custom bras made. If you'd asked me before the event if I'd have found it sexy, I would have said yes, but when it came to it I couldn't see them as sexual because inside it felt that they were 'for the baby' (especially with breastfeeding).
Well, others may disagree with you there; just see the pregnancy thread in the Other Growth topic. Also, although I thought The Man Show was really lame, when I saw it, I heard a line that made sense to me; it was stated that breastfeeding combines the two greatest love of men: food and boobs.
As far as other words and euphamisms for boobs, take a look here and look up breasts:
