i am 20 yrs old, and so is my girlfriend, she was circumsised when she was 10 and we started have sex when she was 19.

when we have sex, she says its like i am touching an open injury inside her vagina so, it hurts alot, she lubricated well and also this has made sex very unbearable for her, how can i stop the pain from happening and make sex more enjoyable for the both of us ?
