Of course, of course! As an asexual person myself, I hate how a majority of romance games don't include more ways to express your love. The scene just always ends in sex or like you said, a fade to black if you decide to do nothing (and sometimes the love interest is expresses disappointment when you do this!) It can feel so awful sometimes.
So when making this game (and any future romance game), it's a goal of mine to include an option tailored for asexual individuals. That way, they can enjoy the game just as much as an allosexual would! :)
