First, and most important, you must have an awesome relationship with your children. I hope my guys stay open and communicate with me even in the teen years. I love them and support them, and so that is something I want badly! Parenting advice? :)
As for your question: no idea about first "peck kisses", that was millions of years ago. First "french kiss" was a guy...name was either Issac or Israel (dunno, one of those 2 Biblical sounding "I" names). I was 12, he was 14. He was more experienced and I liked it when he kissed my neck, but when he french kissed me, I was like "EWWWW" his tongue was doing that dreaded woodpecker thing---hard tongue, in/out/in/out. (gag). I was a bit nervous, it was exciting, and we got teased by our younger brothers afterwards when we got busted. (All of us were in the room playing Nentendo, we thought we could sneak a kiss unnoticed while they played Jaws....it was an unsuccessful mission and I laugh when I hear Tiffany's version of "I think we're alone now" because it was playing at the time). Wow, I've dated myself now. :)
