Any girl that is kissed by her date is sensitive enough to detect that the guy is nervous/ come unprepared. Would you allow that to happen to you? No, I don’t think so.
To avoid that, I suggest you read how to kiss a girl. This one is accessible since you can just download it through the internet. It’s free, and it’s understandable, so there is nothing for you to worry.
By the way, have I told you that the author is a girl and she only posted there what a girl want for a kiss?
