Is it normal or okay to not easily trust someone?

I feel bad asking this but, it takes ma a while to be able open up and trust that person. At first, I don’t normally tell people about my self and what I like and stuff because I know they someone could maybe? Use that against me. So I just asking on here if this is normal and is it okay?

Just a little context: the reason why I don’t trust people so easily at first anymore is because I used to easily trust someone and not a lot of good things happened to me. (Which is fine, I take responsibility for what happened and it’s just that I’m not trying to make the same mistakes again, learn and grow.)
