I think I’m in love with my MC

So, as you all probably guessed by the title of this post alone, I’m a fucking nobody. I’m a loser who has never been in love, or even gotten laid. Considering all this, I decided to write a romance novel – since I’ll never have love of my own. Thing is… I got a little carried away while creating my protagonist and pretty much made Them the person of my dreams. Now all I can think about is having sex with them. So, my question is – how can I write them into loving me back? Or write them out of the book so that I can fuck their brains out? Obviously, I would write them right back in, since the story would be nothing without their presence. After I got my rocks off, of course. Thanks in advance… Any help would be appreciated.
