Pop song from the mid 2000s sung by a lesbian artist expressing that girls like girls

The lyrics go something like “girls like me like girls like you as I like girls too” or “but you still go down better than my ex” or something like that. The song is sung by a lesbian and she is basically calling guys out that say things like “you’re a lesbian just because you’ve never had me.”

Please help, I have the tune stuck in my head on a loop and it won’t quit. It’s so frustrating. 🙃😤
