How do you expect to be any use at all if you're not already lubed up and ready? There's no shame in practicing, you should practice at home, alone, with the curtains drawn and the door locked so nobody will walk in on you. I know you have toys, why don't you use them? Are you frightened? Looks like I will have to teach you to be brave then... Grab your toy and some lube, and then just do as I tell you!
