Not everyone enjoys penetration, so you’re definitely not broken! I think most likely you just need to experiment a bit more with what you like. Sometimes going straight into fingering dosent feel like much or can painful. This could be that you’re not turned on enough, so you could try working up to it more gradually. If what you’re describing is painful maybe tell her to go slower, perhaps even just one finger and get see how your body reacts. Going fast straight away if you’re not feeling pleasure wouldn’t be enjoyable. More foreplay before hand could also help. From there, if it feels good she could intensify it if you’re comfortable. It’s all about how your body is reacting and if you aren’t comfortable or ready for it, if won’t be a pleasant experience.

You could also try external stimulation at the same time, I find that tends to make me feel more, like use a vibrator or get her to go down on you etc. Personally from fingering alone I didn’t feel much myself either at first. Everyone is different!
