[ Men's Health ] Open Question : How often is a human supposed to poop? Not to be gross...?

I saw anothers question and it sparked my interested slash worried me... not to be gross but how often should humans poop? I am 22,M and I go number two like maybe once every two weeks. I have been this way all my life, even as a kid. I will go on weeks vacations and not poop the whole time on vacation. Its not like I hold it, I just don't have to go.... is this bad? Abnormal?
