You are not alone Justme. I have next to no interest and actually think of it as mundane and not worth much thought. Being asexual, most people are quick to say that it just means I havent had "good" sex. I have had sex here and there with people that I had feelings for (mainly just want to cuddle or be held). I just don't have sexual urge.... maybe 10 minutes out of every few months, but as quick as that feeling arrives it disappears almost immediately.
Even in my teen years, people thought I was weird because I had no sex drive. Part of this was being perceived as the wrong gender, but I had also been tested and all throughout my puberty, my testosterone levels were really low, almost in the girl range which can explain why i didnt masculinize, develop very noticeable secondary male sex traits.
