How easy/hard is it to do damage with a dildo/massager? How much can I move around? What should I avoid with it in?

I’m being generous with the lube, yes.

Please answer:

Walking, sitting / standing, stretching… hell, climbing? Is there a range of movement I should avoid with a rigid object up the rectum? Lets say up to a “standard” sized plug.

Say you slipped on some lube and landed directly on your ass with the flare/tab of the anal toy being leveraged by your own body weight against the hard floor to wrench the plug inside you. Anything?

What’s the worst case scenarios or common mistakes. All I’ve ever heard about are:

1) Not using enough lube

2) Using an improper anal toy without flare/tab and getting it “lost up there”

3) Using something too large / long / etc

Just want to know if I should be moving like I have something up my ass when I have something up my ass, or if I can relax.
