I got my partner the Fleslight Flight a while ago and he loves it, the only problem is, after a while it begins to smell funky. He tried using some of our stronger smelling flavored lubes (Intimate Organic Toasted Macadamia Nut lube) and now it smells JUST like the sweet macadamia nut lube even after multiple washes. It's water based and safe for the Fleshlight, and now it smells great Just a little tip!
