Lesbian Sex Tips, Please?

hey everyone! i recently got into a relationship with my amazing woman who treats me amazingly, and we’ve had sex a few times but she took my virginity, and i’m new to everything so i’m not sure how to go about it all. i’ve eaten her out once and she doesn’t want to eat me out (she doesn’t like the taste, and that’s fine with me) and we finger each other a lot, but i’m really bad at it 🙈 she doesn’t like to open up much about how she’s feeling during sex, and i was just wondering if there were any girls out there with tips and tricks for when i am eating her out or fingering her? i’m also a lot bigger than her, 5’3 and i’m pretty thick, and she’s 4’11 and skinny as hell 😂
