It bothers me how I was not his first....

Help, his first time was with a really skinny but busty girl.. Blue eyes pretty red hair etc... We're getting married yes, it always bothers me... Im a 32C she was a 34DD i feel like when he has sex with me he wishes my boobs were bigger we try a lot of boobie things... It makes me insecure i told him before, he said my boobs are perfect & he can cup them perfectly as too huge boobs he had too try and cup it but they'd fall everywhwre... Still i have an ass ;) soo i guess that makes up for it but it really bothers me every now and then... I wish i was bustier... I wish i was his first... He tolf me he almost loved her... When i asked why... He said "cause she was my first" that REALLY HURT :( help guys....
