Now that I know more about upping the size, my other question is: How do you sleep with them in? For me, I’ve found that they just keep falling out. I used a smaller dilator for an hour this afternoon, and then went up 1 size for an hour, right after the smaller sized time. That drove me crazy because I had to lay in bed the entire time and hold it in place. I tried wearing spanks to keep it in place, but that didn’t work Even the smaller sized dilators that I’ve moved on from, fall out. So the sizing doesn’t seem to matter. Any suggestions would be greatly appreciated.
