Fingering🙄

I’ve only recently started to masturbate and I haven’t got the hang of it yet, I’m still learning how to make it feel good because it just feels uncomfortable when i rub my clit & I don’t know why! Also, I have tried a few times to finger myself, I watched porn and even used lube but I can only fit one finger and not even the full way. It feels like I’m just hitting off bone or something I don’t know what I’m doing wrong and it’s frustrating af. Please help me girls 😩

Ps I have been fingered by a boy before and it felt great but i can’t seem to do it myself
