Cowgirl is impossible for me

My husband is a big man 6 feet tall and I’m 5’3. He carries most of his weight in his thighs and some on his belly. He not like fat or anything. Anyways when I’m on top my knees don’t touch the bed because his thighs are big. And I try to put pillows under my knees to raise me up more to help bounce off but I can’t the pillows just slide everywhere. I’d have to be on my feet 👣 bouncing up and down and my thighs get tired after a minute 😂 idk what to do. And I feel bad because he puts in more work for sex. I do give him lot and lots of BJ’s so I guess it kinda balances out…..But still.
