Not Sure if I'm Bicurious or Bisexual

Hello Dr. Betty,
I have a question I am 46 and have been having issues with intimacy with me. I have befriended a woman in her 40's we get a long well she is a lesbian and I am comfortable with her and I have been having vivid dreams about being with her sexually, we have gone to events relating to the lifestyle and I have been feeling very sexual because of them. Exploring my sexual feeling as a women nothing has happened.
