How do I finger girl

So we were in bed cuddling and kissing and shit, and I wanted to finger her so I rubbed her clit like in porn and it didn't work. I managed to distract her from my failure with a really good (so she says) oral sex but I feel rather ashamed. Shit.

fisting: no. Absolutely not. Fist your anus if you want, but not my pussy. no way.
