It used to be that if you wanted a lubricant that was condom safe, you had to use a water based lubricant. These lubricants work well and are safe to use, but they dry out. Oil based lubricants don’t dry out but they aren’t compatible with condoms. Now there are silicone based lubricants like Wet Platinum. Wet Platinum won’t dry out and is condom safe. It’s the best of both worlds. One interesting aspect of Wet Platinum is that because it is not water based it does not dissolve in the bath or hot tub. Only when it is exposed to soap and water does it wash away. Wet Platinum - Silicone Based Lubricant Doesn’t Dry Out. 8 oz. Bottle
