Just my observation, but it seems like stars either (a) come into the business doing a lot of anal (Debi Diamond, Tammy Ann, Vanessa Chase, Jennifer White are a few who come to mind) or (b) start doing (or doing more) anal as they get older (probably because of the money) (I notice that India Summer is doing a lot more anal).
I think it will be a long time (or never) before we see an anal scene from Lexi.
Lexi's always able to make me hot - I want to see her in some bondage stuff. I like the ball gag and tape here: http://galleries.pichunter.com/krawl/305/3054902/index.html but want to see her tied up and used and abused... make them arse cheeks pink!
