personally I tend to wear skinny jeans, packing is necessary because it's all visible. It's really obvious in tight jeans whether there's a yoohoo or a dingdong down there

I hate packing. It feels really fake and unnecessary, especially since I am too small and look too young to have a bulge be proportional. Most pants will have the bulge ironed into the fly anyways, so it really is unnecessary. Some people just find the sensation more comfortable.
