Sex drive

So I'm 16 and everybody talks about how teenagers are supposed to have a huge sex drive, but I don't? People I know have had sex and talk about it, but I'm not really interested in sex. Is something wrong? Have I just not found the right guy? I get really embarrassed when boys wanna do something sexual or want me to send pics, I even feel embarrassed when I get pics. I don't know why I'm not really into the idea of sex, can someone help me out?
