I just asked MY dh what he thought about this.  Since he's a family
therapist, I thought he'd add his "professional" viewpoint as well as
personal.  His comment:  "While bf is 'natural', the pump isn't.  It's also
alot more revealing (ie--both breasts all or partially exposed at the same
time, etc.) AND, there's no baby to look at.  When a woman's bf, the guys can
look at the baby.  When there's a pump, they AIN'T looking at the pump!"

So, there's another unscientific sample of one. :-)
