Does size really matter to a man (like over 35 guys)...?

Iam dating a man who used to date strippers, and I have seen photos of his exes and they have huge fake ****...but me, iam real and not huge, about a 34b...so def not star proportions, my man is 41 years old and Iam 29 and jokingly asked him if i should get implants and he said no, never...but of all the photos i seen of his exes (he mostly dated strippers, bars girls, party girls, drunk/druggie girls and Im the clean living one he has ever dated) but i feel insecure around him and i havent with any other guy i have been with...
