Hush 2 Safe?

Sorry if this is a dumb question. Just got my first plug, a 1” Hush 2, to start. I can get it in, which is great, but once in, I can’t help but imagine it sucking fully in. I’m tight back there, so like, I’m not sure it’s possible, but for ease of mind, is this you safe where it won’t get swallowed in? lol
