I would say Shimimaru draws everyone soft. In the OP manga the girls are the focus, the men are intentionally faceless and ugly (and that kind of objectification is pretty common in Shimimaru hentai) but where the male characters are important - like in Dasei 67 Percent or the hentai with the schoolboy/schoolteacher - the men are pretty soft looking too.
I personally really like how Shimimaru draws dicks - proportions, size, stuff like that. Uh, I do agree in general about women drawing women. Igumox will even draw these super ridiculous, porny hourglass anime proportions and it's still so much better than male artists generally are. Sex Intersect and 11PM Miniature Garden blew my fucking mind the first time I read them.
Apologies for the autism but this is a topic I really want to talk about.
