i like these, but i'm sure you can find many more if you cross out romance and such, and seinen manga tend to be more complex pol-wise while josei are more drama heavy, so maybe something like this: https://www.mangago.me/genre/Seinen/?f=1&o=0&e=Yaoi,Doujinshi,Shounen%20Ai,Yuri,Romance,Smut,Ecchi,Shoujo%20Ai
