Alright so me (21 M) and my girlfriend (20 F) have been together for almost 1.5 years, and we've had a lot of great sex throughout the period. We did have some trouble with her orgasm, but now it's pretty consistent and she's my lil squirt machine 🙂 However though, I've been reading many and many articles on how to eat a woman's pussy, and I have tried that stuff on her, to which she goes it turns me off too much. She thinks I'm not into it, when I am, and I can not wait to hear her moan as I'm eating her out. She also did say it mattered to her that she scratch my back, or hold my arm or something like that so she can achieve elevation into the orgasm. For context, she cums when I finger her, but all the while, she's either holding my dick or scratching my back, or gripping my hair with one hand and my other hand with her other hand. She tells me it turns her on big time to know how horny I am when I pleasure her and see her enjoying what I do to her.
The question here is, how do I show her I want to eat her out, and how the fuck is she supposed to hold my dick when I'm eating her out? (I've suggested 69 but she says she doesn't want to do it.) And some good techniques to eat her out might also be helpful.
TLDR: Girlfriend gets turned off when I eat her, mostly because she can't look at me while I'm doing it, or hold on to me, and perhaps my techniques are not as good.
