Fingering?? Pain?? Wtf

So I'm a Virgin, and I've never really like fingered myself before. I can't fit one finger that's it but like I can't do anything. My bestfriend said that I should try it and that's it's really nice, and that it would help future my future sex life. Will it really make it easier to have sex?? Is there any way to make my first time a better experience???
