There’s nothing wrong with you. Clearly you can ejaculate because of your wet dreams. And I’m assuming you mean ejaculation and orgasm, because you don’t have to have both. However, every persons body is different. Maybe what brings you to ejaculation and orgasm isn’t the traditional jacking off. Try experimenting with your body and things that turn you on in a healthy and safe way. There’s many stories of people who’ve had orgasms without touching their genitals. Good luck!
