Is it weird that I'm fifteen and never had a boyfriend/kissed a boy?

I'm a fifteen year old girl, and I've never had a boyfriend nor have I ever kissed a boy. I mean, when I was twelve I held hands with a boy, but it only lasted a day because my parents found out and grounded me haha - but other than that, nothing. Boy's have told me that they've liked me before, and have called me pretty and stuff, but I never liked them back because I never felt they were the one. I'm the type of person who wants my first boyfriend to be my last boyfriend and the first boy I kiss to be the last boy I kiss. I just want one, I don't want to go through a whole bunch. Don't actually think I could take all the heartache. But still, fifteen, never kissed a boy, never had a boyfriend - weird or okay?
