And they probably draw their conclusions from the fact that I often write about girls. But what does this have to do with cheating and the "slut" syndrome? It's unclear. If they doubt that I can love one girl, be with her, and not look at others (or do anything with them), then that's their right. I know myself better and can separate my silly phrases/jokes from my real opinion.
