|Hint: two is better than one|
Anyways, today's thingamajig could be made of metal or plastic. Both work the same, but I prefer the metal ones. They also come in different styles and sizes. Males tend to use ones that are larger. I guess they like to show off or something. But just so you know, bigger isn't necessarily better! I think using this at least once a week is a good idea. What is this?
