I couldn't help but to look in here after seeing so much talk about pokegirls. And, just to help out Carlissa, here's a little info break for ya:
If you want to play a twenty year old pokegirl, yet have her capable of becoming pregnant, I would suggest that whoever catches her use a Maternity Ball, or have a standard pokeball reprogrammed to have the same programming as a Maternity Ball. The difference? Standard Pokeballs have contraceptives integrated in the program that runs when the pokegirl is in her pokeball, while the Maternity Ball does not.
