At some point you reach an age where all your friends are getting pregnant, but now they're doing it on purpose, ignoring all the advanced technology we invented specifically to avoid that hassle. It's like arriving at their house to find them augering a well, or saddling a goat, or other things people did back in your parents' time. And we're not talking about sex positions.

Your priority is helping your friends against the new invaders. A great way to do that is by buying my eBooklet, "Self-defense Against Babies," DRM-free defensive goodness for 99 cents. It makes an excellent gift, and is as subtle as a velvet sledgehammer when plugged into the intro of a pregnancy article. "Velvet sledgehammer" may also be a sex position.
