To me, it's not the age...its the importance of the person you're willing to give your first kiss to. Because to me, the first kiss is important, and I just think it should be given to someone important too. So just make sure and ask yourself of you really do want to give that person your first kiss.
I think it comes down to maturity. I am 16, I had my first kiss at 13 and the boy was 16. But my advice is make sure that the person you have your fist kiss with is worth it. Because like virginity you can't get it back. Thats why I am still a virgin.
it depends on who it is. and it also depends on how long you have been going together. you dont wanna kiss someone on the first day.... you wanna make sure you are comfortable with them. and i was 14 but it doesnt actually have to be a certain age.
