I love the idea of being with another girl, but am I lesbian?

Hi 🙂 I’m so confused. I’ve always had crushes on boys (on their personalities, not appearances), and now men, but when I get into a sexual situation with them, I just don’t even want to touch them, and all I can think is ‘how absurd’. With the few boyfriends I’ve had, once I’ve managed to ‘get’ them, I lose all interest.
In contrast, I love the idea of being with another woman. I love everything to do with it – the emotional connection in particular. I get all tingly when I read lesbian love stories, and I feel deep down that that is what I want. But I haven’t had crushes on women like I have with men. I think I may have been in love with a girl because I couldn’t stop thinking about her for months, and I wanted to be around her more than anything else in the world. I wanted to kiss her and do everything else, too, but before anything could happen between us, life intervened.
I’m worried that I love the idea of lesbian love so much that I’m just convincing myself that I might be bisexual of lesbian. I know that I’m attracted to personality rather than appearance, but I don’t know what to think. Please please help.
