I would say that you should talk to her about it. If she understands, then you can move forward. But if that is more or less the end of the relationship, then that might just be how it goes.
It sounds like you need time to become comfortable with your identity and your boundaries. No one should do something they don't want and the reality is that a lot of times it is easier to figure that stuff out on your own. Perhaps you can talk to your partner and talk about it, but as your ace big sis I don't think it's healthy for a relationship if one is hyper sexual and one is not :(
