21 year old virgin.

Is it ok to be a virgin at 21? I mean some days I feel ok with it but a lot of the time I'm ashamed. I have never even kiss a guy before. The far I every let a guy go with me is touching my leg or my butt but that's it. I personal can not see myself giving all of me to a guy until it's true love. Is this ok? Are my standards to high?
