I just find it hard to believe this is really that common. Though I'm sure it happens. I never felt compelled to somehow get knocked up without my SO's full consent and approval, but people seem to think women are just waiting to scheme some way to sneak some sperm.
I think making a baby is a huge deal, and I wouldn't want to do that with someone who wasn't ready or wouldn't feel fatherly and supportive.
But how often do you think this really happens or personally know it happened (and hearsay from guys...eh I find that questionable.)
