Figured this is also why works with sumo protagonists are few and far. As most Japanese men don't fantasize about becoming big fat sumo wrestlers. The lifestyle is hard and demanding, plus one doesn't get babes until they're famous enough. Stuff for gay/bisexual men exists where big fat sumo get it on with other big fat sumos yes, but stuff aimed at straight dudes, few and far between. Most tales want average everymen protagonists over someone specialized like a sumo wrestler. Even if the tale somehow took place in a setting that justifies a big fat sumo with big fat babes, it wouldn't sell. Though there may be hope, more series have larger women, so perhaps more mangaka could start presenting sumos as sexy/desirable and perhaps come up with stories of big fat sumos with big fat babes in more mainstream works. Or have mainstream works with big fat sumos with other big fat sumos.
