Tampon struggles

So basically I have been trying to use tampons for years but I just can't do it! I have tried every position to try get a tampon in and it just won't happen. Some people have said maybe it's just because my hymen hasn't broken but literally it won't even go in more than 2 inches so I don't think that's the case , I don't know whether im being stupid or I have a problem ? I just don't really feel comfortable going to the doctors about it because it's probably just me? Any tips or ideas? Thank you for any help ❤️
