What if I'm physically attracted to other people but not emotionally attracted to anyone? Or cant feel emotional attraction?

That would be okay. There are a lot of different kinds of attractions and kind of bonds you can have with people and they don't have to match up with each other and none of them are more valid than the others. Some types of attraction are: Sexual, romantic/emotional, platonic, sensual, aesthetic and many more. If you think you're aromantic, that's an okay thing to explore. I'm currently questioning if I'm on the aro-spectrum! You probably have many questions, there are internet communities that can help you out. Also, you don't have to stick with the label, come out, identify this way forever, never date/experiment, there are no requirements! It's your journey and all you really have to do is take care of yourself and be honest with your sexual/romantic partners. I wish you the best of luck!
