Yes, this is entirely down to preference, but you may find using sex lubes and assorted condoms can make the experience more pleasurable. Depending on where you choose to use your new 8 inch dildo, you may want to make it as smooth and slippery as possible to avoid any friction or discomfort. Lube is great for this and also condoms help your dildo stay as clean and free from bacteria as possible, making it even easier to keep them in good condition.
