I do. I feel like a bit of a creeper, digging up this post. I was looking for something else and stumbled upon it.
Honestly, I'm not sure how anal sex between lesbians would be much different than anyone else's? But that aside.

Usually my partner also stimulates my clit, so I'm not sure if your 1 to 10 applies there. But for when she doesn't, I'd say it depends really. I do sometimes, and I don't others. It's fun, and it feels good. Go for it if you're curious, but be sure to do it right (start slow, use lube, sanitary precautions, etc.).

I'd say anal sex is like any other kind of sex. Sometimes people like it, sometimes they don't. If you decide to try it, start slow. Like most other sexual things, rushing can lead to bad experiences. Good luck!
