Kiss me?

Hi,

So I started dating this guy and we got intimate from the first date. This our fourth week together but we meet once or twice a week. His mom is currently visiting him and hence the limited catch ups. When we recently met last week we again had some intimate moments and he asked me to “just one kiss”. Well we were already kissing but I got the idea that he wanted me to kiss his wily. Is that normal for guys to ask such things. I am highly inexperienced in these things.
