The short explanation
Difficulty inserting a tampon is common, especially when starting out. Often it is because the angle is wrong, the vagina is dry on a light day, the tampon is too large, or the pelvic muscles are tense from nervousness. Aiming towards the lower back rather than straight up, choosing a slim tampon, using it on a heavier day, and relaxing with slow breaths can help. If it is painful every time or feels like it hits a wall, it could be vaginismus, where the vaginal muscles tighten involuntarily, or less commonly a variation in the hymen. Both are treatable. A doctor can gently assess this, with your consent, and suggest options such as pelvic floor physiotherapy.
