Ah - that makes sense somewhat. But there are so many ways to deal with lack of stamina in intimate situations I just wasn't thinking of that as a big hurdle to get over. LoL!
As far as extra routes, I don't know that I'll want to do any more after I've finished the 9th one. Recently I was talking in my Discord server about how I think there are still a lot of stories in this setting and with the cast but I'm not sure how many more stories I can tell about Morgan specifically.
Maybe if I have another main character at some point I can consider other routes! =D
