My friend went down on me?

Last night my friend and I were partying and she said she always wanted to go down on girl at first I thought she was joking we always joke about weird stuff. Then she put on some lesbain porn and said this is what I want to do with you. I was kind of freaked out but just kept on partying. We went out to the bar and got smashed and went back to my appartment and we made out and she went down on me. We both were drunk but remember. I remember liking it but now I feel super akward about it she sent me a text saying she wants to do it again. I told her that it was a drunken thing. Does this mean I'm a lesbain or is she a lesbain so confused!
