A Question about ual Sensitivity?

First of all I dont think you are overthinking. And Grtaz to you for being able to express your feeling so well. I would suggest talking to your girlfriend about this and telling her the same things you have said here. Sounds to me like you already have a good bond and that your love makeing is at a good stage. There really is no need to introduce toys. If you are both happy with your life then I would say leave it as is. In my experiance toys are for people and couples that are looking to put some "spice" back in a relationship...
