I have used them....They are difficult to get into place perfectly, as they stick to the walls of the vagina and it *recommends* you place them as close to the cervix as possible. Personally, I highly mistrust them...doesn't feel like good protection to me. Not enough material to be like a foam and no barrier properties. I've never been willing to try them sans BC pills.

Oh...and per my S/O the guy cannot feel it...although his penis ws a bit "sticky" afterwards...
