How do you *know*

I’m wondering how it is you know you’re a lesbian.

I know I find women attractive and I am sexually attracted to them and have always considered myself bisexual.

However for the last few years I’ve been having doubts about if I find men sexually attractive at all.

Women turn me on a great deal more though my experience with them is limited as I find them intimidating.

But I’m forever checking them out and fantasising about previous encounters.

So eh. How do you know?
