Just need some help

( I’m 17 btw) Ok so I know this sounds weird, but I’m literally scared of putting anything in my vagina. I’ve built up this weird fear of sex ( I’m a virgin) putting in tampons ( never put one in before ) or even a finger, as it just feels too weird, I’m so tight and it makes me cringe ( I think it’s because I’m too frightened it will hurt ) but I don’t know what to do next or ? I just need some advice pleaseeee
