vagina problem/question!

Ok so I can't put anything in my vagina. Tampons, fingers, penises. It's the most painful experience. And like not a normal pain (like there wasn't enough foreplay or insterting a tampon the wrong way) but like a my vagina is being torn open by a dull object type pain. I was talking to a friend recently and she has the same problem. I feel like I should go talk to a doctor. Does anyone else have this problem? Or had it? And does anyone have an ideas as to what the problem is?
