Nylons are delicate and prone to snags. Also delicate: the tissue inside the vagina and anus. If you would like to insert something into one of these orifices, such as your fingers, consider running said fingers across some nylons first. If they snag nylons, they won't feel good in an orifice. Trim nails, buff out hangnails, get some cuticle scissors, use some lotion.
