Anal Plugs and Stretching Let's talk about the safe way to begin anal stretching, using butt plugs. You're going to want a variety of plugs. The grey one I'm holding in the preview clip is an extremely hard plug, without much give, or bend to it, but there are other plugs that have more bend. There's also glass, and silicone, and stainless steel. It is best to use the things that are meant for this, but experimenting is always fun. Just be careful and don't use glass not meant for anal. That could be extremely dangerous, and remember just bc something goes in, doesn't mean it will come out. Use lots of lube especially for stretching.
