Are you tired of shous that have almost 0 understanding of the average adult male human body's basic physiological reactions? Are you tired of shous acting like they're mentally 5 years old when the author claims they're actually at least 20? Are you tired of shous that seem to have completely skipped puberty and remain unaffected by the 10+ years of hormones? Are you tired of shous that lack the basic social and emotional experience of an adult?

Me too.

Here's a list, in no particular order, of novels with a decently mature shou. Please note that MC is not always the shou and ML is not always the gong. FYI: shou/uke/bottom/0 and gong/seme/top/1
