it will come to you. its hard to explain. dont worry though its not like the other persons tongue will get stuck, that rarely happens. its like a normal kiss :)
Average people roughly have their first kiss around the ages of 13, 14 and 15. It should always be your choice to decide whether or not to kiss at that age. 12 or younger, is way too young and just...
well depends what KIND of kiss we're talking about... if its like a peck then yeah sure go ahead and even if your tongue will be involved then sure you hear the horror stories about tongues and lips...
