Fake Boobies and Relationship (Opinions please!!!)

I have gotten a breast augmentation recently. I am so happy with my choice but now that they are there and more to "show off" (saying lightly because they aren't huge just normal) I think my boyfriend is concerned that I want to show them off to other guys. Don't know how to make sure he knows it's for me only and not to worry about me being a "show off" Opinions?!
