During an "wild" phase with DH,yes, we did. And while it hurt at first (a lot), once I got into it they were the most powerful orgasms I've ever had.
I really don't think it's healthy, however, so we haven't tried it in 5+ years. I worry about tears, stretching and infections. It was really just an experimental phase.
ETA: can't believe I just admitted this on a public board.....
