Why is everyone so surprised? It was so obvious the moment that Hojo BLUSHED as he was checking out that fat guy.
The least that Hojo can be is Bisexual...maybe Sadako straightened him up. Although I'm not sure that he kissed her intentionally...she just crawled on him and placed her lips against him.
It's more like, "How much he likes girls" rather than his ability, but it definitely says "Onna suki".
