Will my boyfriend be disponted if he touches my breasts?

So i have pretty damn small breasts... Like 32A and ive always been a LITTLE self conscious about that hut bleh i dont really care because i tell myself the rest makes up for it hahaha. Except when it comes to my boyfriend. Once while talking the subject of breasts came up and he said that megan fox has too much, in his opinion. Last night, while making out, he began to gently pass his hands over or around my breasts. Now that itself does not bother me at all, but im scared hes going to think something like: damn theres hardly nothing to feel. Im worried hes disappointed or doesnt like it or idk... And also, for the futur if we get there, i would be terrified to show my nakedchest to him because they are small... Any advice? What do you think? Am i worrying too much?
