That's a fair point. I mean, I wouldn't have to choose. I would just be given the power if that was the case. Though a lot of people would probably be down for it. It would lower the birth rate tremendously, which I wouldn't be against.
@Paul_Tromba It's more along the lines of those who want kids are going to have them, and a lot of people are already willing to give up careers and many other things to have children. Giving them powers to remain virgins might just mean they delay it to do work before having them. I don't think anyone wants to be a wizard/hulk for life.
