Tampon trouble 😫

(UPDATE) Thank you everyone for all the help! I got it in! It felt weird at first but I’m proud of my self. I just conquered my first tampon yayyy!

Ok so I can’t get my tampon in and someone recommended that I use coconut oil but I don’t have any coconut oil. What else can I use? Can I use Vaseline or would it irritate the area? Would I put it on the tampon?
