too tight

So everytime I have sex I feel like I am super tight like virgin tight and I am 25( and not a virgin). BF loves this but i tend to get pain/ tearing feeling on the lower skin part of my vagina... Even if he is gentle.
I know I know..... Poor girl has to have sex with endowed guy and wow him with tight vagina.... some one call the wambulance. 
I use lube and get wet easy so any other ideas to help me????????
