Nothing wrong about it at all. Thats about you being happy, your priorities, you living your life, not that people. There is nothing "that odd", and if you wont have any serious relationship in next 5 years even, that gonna be up to you only aswell. I have friends who never had a relationship aswell. IMO thats only up to you whre, with who, and what kind of relationship to have. No one else. People just love to be ignorant for some reason.
