I've read Jack's thread and it has some good advice and truths but in my opinion there is missing information where it's most important and it is very, very generalised, so I find myself disagreeing with a lot of it. There is no one size fits all answer.
Anyway, If you haven't found it, give it a read, it's here:

She wasn't ready. (I personally believe) you cannot "make her ready" with a working or spell, this could backfire. The only thing that will make her ready is patience and time. And making her feel safe. Have a talk with her and discuss her boundaries. If you don't want to do that, be fair; detach and let her know you're leaving. You can find others who will have what you want. Otherwise, you can ask certain demons for help if necessary - if you are dedicated.

I'm surprsied no one's mentioned this... the fact that she let you kiss her means she likes you, the rest of you "not feeling it" is insecurity and projection. She didn't want to be rushed and said no. She let you know that she knows her body and has her boundaries. That is a totally common thing in monogamous people. I don't know if I got the wrong impression but that's how things seem.
Have you considered taking things slow?
Anyway, if necessary, here is info on detaching:
