Gun Oil is a popular sex lube that’s been around for almost two decades, pumping out one of the best lubes there is. With added Aloe Vera for skin protection and ginseng and guarana to stimulate circulation, while enhancing both endurance and sensation. This is the water-based version, but you can also find Gun Oil as silicone-based on the store page. Silicone-based ones last longer than water-based ones and can be used in water, but it’s harder to clean off after use. Some people may also be sensitive to silicone. This is a big bottle that contains 480 ml / 16 oz of premium lube, having a very high rating of 4.7 out of 5 stars.
