The Hot Lips cock ring from Rocks Off Limited was a miss for us simply because the material and design clung to my husband's skin and made using this cock ring painful. He does have pretty sensitive skin, especially there, so your mileage may very. Never fear though, even if you can't use it on an actual cock the Hot Lips perform nicely on a vibrator or dildo. It's a great way to spice up a toy that may have otherwise seemed boring.
