Ashamed of myself

So when I see mamas posting up close videos of their babies munching on their boobs, it makes me feel super gross and disgusted. I am pregnant and nursed my first two kids and will nurse this one as well. What is wrong with me? I would never say something to a nursing mama, and completely support public nursing, but I don’t like seeing it’s mouth all wrapped around the titty going to town. I’m going to hell, aren’t I?
