Unlike my other work, Nowhere Girl, Lucy (or however you decide to name her) is a defined character within Animal Lover with attributes and traits outside of the decisions of the player. Considering the extremely gendered nature of the narrative of Animal Lover, extending into America's history of gender relations, I did not feel as though these characters would have achieved the same narrative were the main character to be male, much less so had the same kind of incidental dialogue.
Granted, Nowhere Girl has a female protagonist, so in terms of great non-straight VNs with male love interests, I recommend Hustle Cat. The writing is cute, I'm a big fan of the art, it's a good time all around. 2064: Read Only Memories also has a plethora of gender and romance options and a pretty stellar writer at the helm. It's not a VN per se, but it's still a fun point and click.
