Have you ever had a thought that you might be "bi" or gay/lesbain?

I was having a conversation with an old friend of mine who recently told me she has outed herself as a lesbian. I have nothing against it and i was proud that she was happy.

i asked her how she knew she was or what made her think she was, she told me she always had a little idea in her head she might be but was never sure. one day she was watching a tv show and it really got her thinking so she joined an online thing and meet a girl through it just to see if thats what she liked. ended up that she did.

Have you or anyone you known ever felt that way ?
