A LITTLE TO MUCH TMI

So ever since i had my son (4 yrs ago) when me & my husband have sex this part on my vagina hurts so bad. After awhile it starts to sting & then get really irritated to the point it takes me a-couple days to feel better. Now last night we did the nasty again. & i made sure things were wet enough & this time he went slower then usual hittin it from the back slow & deep. & again it starts to hurt & sting. No matter how gentle he is down there i always seem to have this problem.

Could it be from tearing when i gave birth to my son?

Or what? Because for yrs now sex is juss to pain full for me😒 & i likes to get my shiit rocked😬😂

Any help! Please & Thank you 😊
