kiss

I do hope you're also 10 years old, or close to it.

Which would make you officially too young for this site (we are age 13 and up).

And if you are old enough for this site, well, unless you are talking about nonromantic stuff (e. g. kissing your daughter), then this is just plain creepy.

You don't need to kiss anyone when you're 10.

At ten years old, you have no business kissing someone. Be a kid; don't concern yourself with matters that will be much more meaningful when you are a teenager or older.

I would suggest the person who can give you the best advice on how to kiss a 10 year old girl would be her father.
