To tight of bondage for a period of over 1 to 2 hours can cost you a limb. Moderate bondage can be taken 5-6 hours or when the apengades turn purple from red color. You must be watched when bound or gagged. You never know what your panic level is. Be careful. The whip leaves marks but you will recover from it as you will for a paddle. A Dom should never leave you alone with your mouth gagged tightly. emma
