I keep falling out when she's in reverse cowgirl position. Is anyone a fan of it?

It's not an ideal position. The simplest ones are the best. Riding takes a lot of practice, getting the height right consistently is tough.

It's good if the guy is hung big, downward curve, and really hard. I know, very specific requirements. But when all that happens, it's a really intense angle but can control it, if that makes sense. From kneeling, I can't do the squatting thing.
