Is it normal that i never tell any of my friends about my crushes?

I have plenty of friends who I can confide in, but for some reason I can't bring myself to confess about the guy I have a crush on and the relationship that we're beginning to have. It's really weird - I've never been able to talk about this kind of stuff even though my friends do all the time. Even though I do want to talk about him and discuss whether he likes me with my friends, I just kind of find it oddly embarrassing? I didn't even tell them that I went on a date with him and once, when my friend asked if I liked him, I lied and said no even though I totally do! Is there something wrong with me?
