Positions for height differences

My man is 6ft 6 and I'm 5 ft 6. We can't do doggy at all because he's too tall even with pillows under me and him standing on the ground with me on the edge of the bed. I have tried riding him but it's like I can't move. Hes skinny but it's like my hips are spread too far apart to be able to move properly. We currently only do missionary but I like changing it and wanna know your opinions on positions for tall/shorter couples. Thanks!🤓
