Want to lose my virginity but I’m too tight!

I never used to finger myself and now I’m thinking that I’m going to have to. I’m still confused on where I should finger my self, don’t know if this is the correct hole.

I tried fingering myself recently, where I thought was the hole. I can’t even open my legs wide enough and I squirm everytime I try. Is this even Normal or in I just too sensitive.

Shall I buy dildos and try using them? I’m 20 years old and need advice, I’m a virgin.
