This is a game for kids all ages. I doubt their parents want them to play some game with mating involved. Hell, I don't actually wanna see that and I'm 15. But then again, I'm more for roleplaying and preset making than inapropriate things. Plus, if you want to be 'pregnant' just change ur weight. Sure, it doesn't look like it, but we srsly don't need to see large stomachs. Knowing my luck, people will go on about fat jokes and stuff. And when you say pregnancy, the person might be to underaged to figure that out. And then the bird & the bees is told. >.> So I say definite no to mating and pregnancy in general.
