Not Interested in Dating

I'm a sophomore in high school and a lot of my friends and the people around me are all interested in dating. I don't get the big deal? While I think that some of the things couples do are cute (like cuddling and surprise kisses and stuff) I could never see myself doing that. To be honest, the whole idea of dating scares me but lately, especially in the last year, I've been getting pressured a lot to do it. A lot of boys have asked me out, and I feel bad for saying no, but I'm honestly just so scared of the idea of dating? Is there something wrong with me?
