Hey Kaika,
You are definitely not alone in this. I'm 24 and have rarely dated. I'm in graduate school and have plenty of opportunities to meet people, but haven't really felt the need or desire. I figure when I'm ready it will happen. It can't be forced anyway. As for the teasing, I totally understand! People are shocked when I even mention the possibility of having some romantic relationship. But it's okay. I've got stuff I want to do in this life and so I don't feel like I am missing out on way or the other (unless I'm really depressed, than I'm a lonely). I also sometimes feel relieved when I talk to my friends who are having relationship problems or so desperately want to be married that they can't function without being attached to someone and I realize I don't want to be that way.
