I have a 7 inch flexible dildo and when I try to insert almost all of it then there comes a point where I feel some kind of resistance inside. Sometimes I am able to work around it and after a while I can get it all in is this dangerous? Is it possible that you tear something or would you experience noticable pain as a warning sign before this happens?
And is it actually dangerous to flex your PC muscle while you have a dildo up your ass? Cause I tried this and it felt pretty good. This way the rectum contracts and it gets much tighter and you feel more but could this be dangerous somehow?
And I also wonder are there any risks involved with using anal vibrators for a long time like for example 1 hour without taking a break? Could the vibration somehow be unhealthy for the tissue in the rectum?
