I don't think that's true. I think if you said all girlfriends lie to their boyfriends people would agree with that as well because it's not necessariy gendered; people lie.

I've looked at both of your sources. The Scotsmans' poll we have determined and you have conceded is non-scientific. The Psychology Today is better but again only surveys 400 women at 2 community colleges. The report there is that ~33% say they they have risked pregnancy without "discussing pregnancy with their partners"; that could mean anything (we just started dating and it would be weird to bring it up, etc) and it doesn't necessarily mean deceit although it could. Even then, that's only 133 women reporting. Not exactly conclusive.

  I think you are inferring that people are attacking you on the basis of gender. All the responses I've seen have been courteous. The issue is only "controversial" because, again, you fail to provide reputable sources. If you can produce more sources like the Psychology Today one, you might have a leg to stand on. I think you are overblowing the rate of women who want to get pregnant in secret or against the will of their partner. I'm not saying it doesn't happen, but I think that you need a little more data to constitute "a significant percentage".
