I wonder could insert a dildo or vibrator into the anus cause any problems or damages?
For example could it make hemorrhoids worse or could vibrations in the rectum cause damages?

What I also wonder, does the ass produce some kind of "juice" when you somehow stimulate it?

What I also noticed is that after using the vibrating razor and holding it directly onto my ass then all of a sudden a few hours later
when I was lying in bed I felt some kind of sensation down there. Is it possible that you can somehow "awaken" your ass and once it's
been awakened it suddenly starts to tickle or twitch and suddenly do things which you cannot control? For example could using
anal toys make the anus more sensible so that when you're for example driving in a car and there are vibrations then you suddenly become
aroused which normally would not have been the case? That wouldn't be good.
