T-t-tampon? Help inserting a tampon.?

5th try at inserting a tampon. I know where the vagina is. My hymen is not covering the whole hole. I've had my period for over 3 years now. I'm a virgin. I know how to do it. I'm pointing it at my lower back. I'm using a slim easy glide brand at the smallest size. I'm calm while I'm doing it. Yet I still can't get a tampon it! Ugh! Please help.
