Using these shorts is easy. First, put them on just like regular shorts. The 1.5 - inch silicone O - ring is where you can attach your dildo or packer. If you want some extra fun, insert vibrating bullets into the inner pockets (remember, the bullets are sold separately). When it comes to maintenance, simply throw them in the washing machine. As for precautions, make sure to check the attachments for any signs of wear before each use. Also, avoid using harsh chemicals on the shorts as it might damage the fabric. These shorts are designed for your comfort and enjoyment, so have a great time with them!
