As a simple lubricant it is amazingly good. Soft and silky, and not tacky like you might assume with a novelty item. Me and my wife like to warm the bottle in a cup of water before using it with Doc Johnson's Bust it *****. We also found that it is surprisingly concentrated and easiest to use when simply mixed with water. We found the best mix is about 50/50 meaning you are actually getting around 17 oz once mixed. Even diluted it retains it's realistic ***** appearance. The first time you smell it, you may think it's odd, but not offensive in anyway. We both agree that this product is our go to for simulated *****, and despite it's authentic appearance my wife has not gotten pregnant! That's a another plus!
