Vagina pain

I just wanna know why my vagina hurts so much after sex. Recently it's been hurting and I don't know why. At first it was because I thought he used the condom fire and ice and so I thought it was Bc it was that type of condom but he used a regular one today and it still hurt. Other times we've had sex we had no problem can someone tell me why is it normal. Last time I had sex was about abt 3 maybe four weeks ago (( it's burning and its dry rn))
