sex issue pls help🥺

okay so i’ve been trying to have sex with this guy that i really like for a while and I can’t make it work! I trust him and i am relaxed when we try but it won’t go in. i’m a virgin and i know to do tons of foreplay and stuff but it isn’t working. the last time we tried it ripped a little🥺 it hurts like hell and i’m tired of not being able to do what i want and i really just need advice :( are there certain positions or things i can do to help the process?
