> I for one welcome our new robotic overlords and agree that it isnuncomfortable to be reminded that my favorite sexual objects are in fact meant for other purposes as well. So you would be "uncomfortable" having a female coworker that was using a breast pump? No wonder this industry has such a gender problem!
If she was doing it in an open office for everyone to see? Probably, yeah. I wouldn't say anything, obviously, but I definitely wouldn't be as comfortable with it as I would, say, a sneeze. I'm sure my female coworkers wouldn't mind vigorous nutsack scratching out in the open for all to see would they? It also is a perfectly natural activity and often necessary. But hey, I also get annoyed at people who chew loudly.…
As for you scratching yourself: that is not something for which there are no alternative options, however, breastfeeding a newborn happens frequently and has to happen when it does and no amount of discomfort on your end will change the fact that it is as normal as you eating a sandwich or drinking a glass of milk.
If a woman is doing it 'in an open office for everyone to see' it may mean that your society is more accepting than you think, or that no more suitable alternative was available. If the lady is comfortable with it and you're not you could simply ignore them?
