To dominate, to being dominated(submissive)Help ladies!

Hey ladies! I really need to get some advice from you all. My husband and I have been married for 5 years together for 6 and have two children together. We finally went to the adult store and got some toys and stuff to try out which is a huge step for us. I really want him to dominate me and I would love to dominate him. How do I go about talking to him about this? Without feeling shy? And without making him feel uncomfortable? I would feel embarrassed if he said no to doing those things together. Are any of you a submissive or a dominate and how did you start? Thanks for your help 😊
