Is something wrong with my vagina???

Help! I’m a virgin and while clitoral stimulation feels nice, sometimes I want to be penetrated. But here’s the things, penetration hurts. I’ve never had a problem sticking a tampon in or anything, but when I go to finger myself there’s a bit of pain about an inch, maybe less into penetrating myself. This is only with one keeper. Usually if I reposition myself, relax a little more, and move my finger a little lower it’ll slide in just fine, but anything bigger causes a little bit of pain. Is this normal??? I’m worried something is wrong with my vagina 😰 I am really nervous about penetration so maybe that’s not helping.
