Is it wrong to have a preference?

What's your views ladies? We are ttc our first. We would absolutely love a boy or girl but if we had the choice we would both prefer a boy. Sometimes I feel so guilty for saying it. Also, with this shettles method of having a boy you're supposed to hold off from having sex until ovulation. But I don't want to narrow our chances of actually getting pregnant. Sometimes I just think whatever will be will be. Do you guys believe in this method or do you think it's pure 50/50?
