The concept of my story world is extremely embarrassing and I feel ashamed of it, but I still love it. What should I do?

I had the idea for a story for awhile now, and it has been an idea I've had for well over a year, I don't know when exactly I got it because I write in a diary and I lost it a long time ago. I remember I wrote the date on it but not the month or the year. I remember that the date was the 10th, but have no idea when I wrote it down. <br><br>I have wanted to write this story, because it is a fantasy story and it's the first time I came up with an idea for a fantasy story and I've always wanted to write fantasy, but the idea is embarrassing and I feel ashamed of it. <br><br>I'm pansexual and I have been attracted to fictional characters since I was a teenager and from what I understand it's normal for many people who are part of the ace/aro specrum but I also have sexual attraction. <br><br>My idea is for a high fantasy story that is very similar to the Wheel of Time by Robert Jordan except instead of the magic system being channeling, it's based on pansexual arousal. I know that concept sounds embarrassing and ridiculous to people and I feel really ashamed about it and have thought about changing the central plot of my story. <br><br>I know that my idea is stupid, but I like the idea so much that I have been working on my story world since I came up with the story. I have been building it for well over a year now, and have made it really complicated. If I was to change the main plot, I'd have to change my world entirely and I feel like I'd be having to do the same work all over again. <br><br>I know that my story is stupid, but I really want to write it. I want to write fantasy, and I don't have any other ideas for it. I have a lot of other story ideas I want to write, but they aren't for fantasy. I want to write fantasy so badly, but I feel so ashamed to write this story that I've been putting it off. I still continue to work on my story world, but I don't even know if I'll end up writing it because my idea is so stupid that I feel ashamed.
