Boyfriend wants to buy us a toy?

My BF is a dom and wants to start to introduce me to things in the bdsm community. I’ve agreed to this and told him it would take time but I am fully committed to trying things that could be enjoyable.

He wants to go shopping together and buy us a toy to use in the bedroom. I’ve used toys personally in the past but am unsure what would be a good “couples” toy. As a beginner, what are some good recommendations as a starting off point?
