Pain during sex

Haven’t been having sex for very long but done the whole shabang quite a few times but it still hurts during penetrative sex. People suggest that I’m not *ready* down there but i am, also there’s no lack of foreplay and it’s not that I’m too tense. Wondering if anyone has any suggestions that might help or explaination for it?

Also if it helps the pain is further inside, not just the vagina
