How do I approach the subject of my sexuality with girls?

I have a fluid sexuality and mentality. I am masculine and yet feminine. Androgynous. And I don’t know how, or when to tell someone I am interested in about this.

It has not been easy to accept this, because at times it meant rejection from people I love and it has left an imprint that perhaps I am not worthy of a woman’s love.

I feel bad about my ex-girlfriend who, like me, didn’t know about my proclivities and once she was aware (before I was) decided she couldn’t stay. I don’t want to mislead anyone anymore. So I appreciate your thoughts.
