Fear of going to hell because of lust

I’m still a teenager, but I feel a lot of sexual desires (maybe because I’m a virgin and have never kissed anyone) and I can’t go without being satisfied for a long time. But I know that this is very wrong, it is a sin and God is not pleased with someone doing this (masturbating) but I don’t know what to do, I try to stop but I can’t, he is stronger than me. I didn’t watch pornography today but I read an erotic story (I think it’s the same thing) but I don’t know what to do, I don’t want to go to hell because of this, I’m really scared.
