What do I do?!

This is a bit embarrassing but how do I masturbate? I’ve only tried a couple of times before. I don’t really know what to do or how to make myself feel good. I’m a bit scared to put my fingers all the way into my vagina and every time I try it just feels weird and tight. I always feel like I’ll hurt myself if I masturbate but at the same time, nothing I do makes me feel very much. I’m so sorry for the TMI but I’m just a bit confused. I would like to learn how to pleasure myself but I really just don’t know how. Any tips or tricks for starting to masturbate are appreciated!
