Tampons hurts as hell
So I am a 19F virgin and have a normal period cycle. Last month i tried using tampons for the first time and it was a nightmare for me. I used on the second day of my period and followed all the instructions like the correct position, correct angle, enough lubrication etc. But gosh it only goes for a certain length. After inserting like half of it it doesnt go any further and when i try to do it it hurts as hell. But however i completely pushed it inside but gosh half of it came out right after i loosened the pressure. I do swimming so this is my only choice. In my country only the brand called MARVEL is available and also it comes without an applicator. Is it because of my hymen? Plus Ive been experiencing some kind of pain in my vulva only when im on my periods. Ive haemorrhoids and this pain is similar to the haemorrhoids symptoms but only happen when im on my periods. please give me some advice girls
