In NSFW 11, Steve Japple was confirmed to be gay (though it was ambiguously framed), as evidenced by his utter shock of his beloved Purple Pencil being a girl, which makes sense considering the old Apple logo was rainbow-colored.
Another indicator is while he gives Purple Pencil monikers such as "Senpai", "My Queen", "Waifu" and "Mommy", Steve Japple had not once called her by any pronouns throughout the webcomic. And if we're really stretching it, the mentioned nicknames can be gender-neutral since anyone can be called anything by internet standards.
