The problem is not yours you have been lied to. Your boyfriend is the one w/ the problem. It is not that your vagina is loose it is just that your boyfriends penis is slighty little.

Just like there is large penis there is large or looser vaginal.

It's possible your boy friend may have small penis but if has average size which is 6-7 inches and girth should be 5 inches or so and he feels nothing. Well..you got a loose vaginal.
