your vagina is super elasticy and wil stretch to comfortably fit a tampon. the problem is probably that you are dry and its hard to get ANYTHING IN LIKE THAT. try to use a water based lube or , i know it sounds gross, but saliva works great too, around the applicator. my cousin told me this when i was 13 and it worked until i got the hang of it. it will slide right in and you'll be able to find a comfortable angle. dont just have sex to fit a tampon, seriously, thats just silly. goodluck
