If you're into cock rings, here's a set that should turn on your partner in a big way, while keeping you hard for what seems like forever (but as the box warns, don't wear them for more than 20 minutes). Each ring in this set of four has a different configuration of nubs, ribs or spikes, and depending on your preference, you can wear just one or all four. The larger your dick, the tighter these babies will feel, and yes, you can use them with a condom - but make sure you use a water-based lube. Next time your honey says, "Ooh, what have you done to your cock?", you can thank Doc Johnson.
