birth control
"I was on Nuva Ring for over 8 years.  I have horrendous periods, so my OB told me to insert every four weeks and skip all but 1-2 periods a year.

It worked great as far as birth control and controlled periods so I didn't have any.  I couldn't feel it once I got it in right, and really didn't have a whole lot of other problems.

The only reason I am switching is because the ring can cause cervical erosion, especially if you have very sensitive skin.  This results in pain and bleeding during intercourse.  It's a relatively easy fix, they cauterize the touchy spots, but still very awkward.  I am now switching back to the pill to see if I can find something that isn't so hard on that tissue."
