My husand and i have been married for two years.. we just had a baby 7 months ago, and now the sex has gotton to where it hurts bad.. when he is trying to go back and forth it feels like a knife is cutting my vaginal wall... we dont use condoms cause i am on the pill. but what could make it hurt so bad.. i dont understand it there is nothing on his penis when he penatrates me, and there is nothing inside me.. if you can help me i would greatly apperciate it alot. thanks
