Brandye, is the following at all significant minus disease-transmission concerns?
"Recently, Phillips et al. demonstrated that rectal application of N-9 resulted in sloughing of surface epithelia. Hyperosmolar fluids have been shown to induce similar changes in the distal colon. Because many water-based personal lubricants are hyperosmolar, such formulations, applied rectally, may induce similar damage."
