That comic sounds like it could have some very unfortunate implications (namely that aromanticity and asexuality are bad and make people boring, and are problems to be fixed, and that sex and romance are one and the same). On those grounds alone, I would change the story. You would be perpetuating a Hollywood cliché that some people already take to be true, and it's a rather harmful one at that (just ask any asexual how they were treated when they came out as such).
Not every story needs to break clichés to be original or enjoyable, you know...
I mean, I can't exactly comprehend or get interested in this particular story, but I'm not generally a fan of most "The main character is the author" stories.
Also, OP, it seems odd that you'd write about yourself in the future. It's really hard to gauge how you, personally, will be in the future. Generally it's easier to either make up a whole new character who
could be you, or were you in the past. But in making an original character, you also have more freedom to do whatever you want with them.
Also, a boring character is, as you might guess, boring. Unless the boringness is a character trait you can make interesting (sounds paradoxical, I know), or used as a sort of foil to the interesting things around them.
A great example is Arthur Dent from The Hitchhiker's Guide to the Galaxy, a perfectly normal human being who manages to adapt well to the completely absurd environment of the rest of the galaxy after he is thrown into after the destruction of Earth, but at one point actually becomes a revered person on one planet as... a sandwich maker.
