We kissed before I left home we have only met 4 times so far?

Is this soon or good? We haven’t labeled each other yet. He is on a business trip for some days. We are still getting to know each other.. but what worries me is that if kissing and not labeling each other a girlfriend and boyfriend is fair?
How long should we wait for that?
I have only had 1 boyfriend before and we waited almost 7 months to even say ok we are in a relationship now..!
