Nope, I'm the same. Almost 21, never dated. Heck when two of my siblings and my mom were my age, they were married and had a kid. I'm fine with it though. I don't see myself getting into a romantic relationship, at least not in the near future. :)
No, I don't think it's weird. Some people get into serious relationships when they're young teenagers and others don't start dating until much later in life and others have no interest to tarehe at all. Everyone's different, wewe just gotta do what wewe what wewe want to do so wewe can find that guy who wewe will be happy with for the rest of your life.
No, I'm going to be 20 in December and I've never even been kissed. There's no rule that someone has to have a boyfriend au girlfriend kwa a certain age.
