Is SO trying to suggest anal?

Lately my SO has been making side comments about going further with sex, and keeps mentioning lube whenever we walked past it in the store.
We don't use comdoms lately however when I got home from work today there was a new box of comdoms on our bed and a bottle of lube. We've never had a issue with anything being too 'dry' as such during normal sex, so this is all I can think of?
I've told her a few times I'm not really keen to try, but confused on what she's trying to get at?
