We went back and forth on it for a while and it mostly came down to the experiences we had to draw from and a lack of confidence starting out. While we'd both dabbled in erotic fiction, we'd never attempted anything on this scale before, and so we wanted generally to keep the perspectives grounded to our own experiences, and that created a slight problem for M/M pairings because it was really the only perspective we lacked. I guess the short version would be that as a heterosexual man and a pansexual woman, we felt that any M/M content we wrote would probably be the easiest to critique, and given the inherent insecurities of working on a project like this we decided to spare ourselves the risk of fucking it up.
Stuff like Markus being pansexual is mostly a holdover from when we were still considering M/M content, and we liked it for his character even if we never gave the player the option of reciprocating. In hindsight, we should've just gone for it, and moving forwards we have the confidence to write things outside of our experiences and accept that we can draw on others if we're ever in doubt, or even look into hiring writers for specific scenes that fall outside our area of expertise. There's really no need for us to limit ourselves at this point. - Hallows
