Yep, ya bet you, try one, but I would buy a large size baby one prefably 12+ but 6+ can be good, my mouth is small and I am female but I don't know if you are male or female or have any idea how big you are.
If you like it then I would move on, I will move on once I get enough money.

To adult sizes, I am glad you are taking the path of being a adult baby and being yourself.
