He didn't say that although my impression was he did fancy him quite a bit. He did say, I'm assuming jokingly somewhat, that he thinks one of the reasons he likes to write scenes for hot guys is to get them to like him and he writes about Gareth specifically in that context. Every time he mentioned Gareth he mentioned how hot or sexy he thought he was much like with Tovey, whose arse he was particularly fascinated with. That just seemed to be a thing with him whenever he mentioned anything about the guys who've appeared on his shows, like James Marsters, he usually mentioned how sexy, hot etc. they were.
