ok I consider myself straight, however, I often find myself fantasising about having anal sex with another guy and getting turned on by it, what does this mean?
You could be Bi. Before I even started to consider that I was Bi, I started fantasizing about "being" with another girl and getting turned on by it. It was only when I read online about other people having similar issues that I thought I could be Bi. Or it could be that you are experimenting, I know everyone says that, but it could be true? It is really natural for people to think of being with someone the same sex as you. So before you consider being bi, give it a decent amount of time. Either way, there is nothing wrong with it at all xx
