What does she really want??

So I’m lesbian. I’ve been with my fiancé for about a year. She’s more like a butch and I’m femme. Our sex life was pretty good but now there’s just this awkwardness. She is the one that likes to give than receive. But she just told me she would like to receive more.. so I asked her what kind of things does she like being done to her and she said idk because I’ve never really thought about it since I’ve always given, which I understand. So now I’m just confused. She’s the first girl I’ve been with sexually and I’m just scared and intimidated bc I’m not used to women. She said nipple play doesn’t do much for her.. so do y’all have any recommendations on what I could do to turn her on and make her cum??? And also I feel like a newbie and idk what the hell to do with a vagina especially hers. We’re totally opposite, I like direct clitoral and hers is too sensitive for that so like idk how to even finger or go down... I know this might be a little tmi but I’m just stuck...
