What Does It Mean?

A couple of months ago I let my uncle bone me. I’m not gay, and neither is he really. He’s in his fifties and divorced, and he discovered that occasional he enjoys having male sex.
But he was feeling n the mood and he talked me into getting naked and messing around with him. I didn’t mind that, and then he wanted to get carried away I let him fuck me. I was so amazed by how stimulating this was, feeling his erection going in and out of my butt, and while he was doing that to me, I started ejaculating. I was so surprised!
I had never thought of myself as having any gay tendencies before, but now I’ve let him fuck me several times and I have thoroughly enjoyed this. Does this mean that I’m gay?
