i doubt that there will be artworks of the males made. simply because if you make the artworks of futa characters, more people are going to like them, and so it's easier to make them. Something similar with women.
You can steal read through quite a few scenes with males that aren't drawn. For example:
• on Town Square at nighttime if you have low Purity you can suck dicks in the alley;
• in Brothel with low Purity you have various scenes with males;
• if you lose to Warlock in her mansion, you can choose loving anal. After that you can return and choose male partner. Or if you recruit Alma, you can ask to call her friends for you;
• or you can lose to Ghost, actually this outcome has animated art with male characters.
• you can also steal a bunch of things and get fucked and Trudy and Kylira with you
• you can have Trudy in your team, go to first town inn and sleep alone. There you can peek a man fucking Trudy. Choose to wait at first, at second choice you can join them.
