I 18M made my 18F uncomfortable accidentally.

This all started last weekend, we were coming home from an event and when we got back to my house (we don't live together yet) the fingering was like nothing before she was so hot and wild and it put her into a place I'd never seen before she was so horny. Which was something she never showed before. She is usually very sexually reserved we have been together for 8 months now and started doing sexual stuff around halfway through our relationship. Then the next morning is what really got me it was another amazing session that we had never had before. Since we are long distance she goes back too where she lives 2 hours away during the week and we facetime every night. The day after she goes back to where she lives I seduced her over the phone not on facetime and for the first time she masturbated as I walked her through it. But recently after all the amazing things that happened we had been talking a little bit dirty and I had asked if she could show me something over facetime something she's done before. After that she said no and said that thats all we've talked about recently and that I had pushed it to far and made her uncomfortable. This made me feel terrible and crushed because I love her so much and don't want to fall into that category of guys.

I think its mostly because of my sexual frustration because our relationship is only sexual for her. She is the receiver of all the love. I've eaten her out fingered her dozens of times but she has never done anything with me. I mean she's had her hand on my area and she hasn't done anything with it then she just gives up even though I try to help her.

Right now I'm just trying to be patient and stick to my commitments of being the best I can for her (we are planning to be abstinent until marriage). Its just difficult for me considering my past girlfriends where I've actually been able to have sex. I know she is different but it doesn't feel worth it without any love from her on the sexual side. What do I need to do to improve and fix what i made uncomfortable.
