Help..? Can't insert anything

Anytime I try inserting anything in my vagina, I can't.. Whether it be my fingers, objects, nothing? I rub my clit and it feels good but I really want to be able to insert something so my first time with an actual dick won't be so Bad. But it hurts and like won't go up. I had a hymenectomy so I have no hymen, so that's not the problem..
