Kissing your hand is sooo different from kissing another person. Honestly, I wouldn't bother with the hand. I'd tell your friend to just wait until he meets someone, then practice with them! A lot of people his age haven't kissed anyone yet, and first times often are awkward. So he doesn't have anything to feel weird about by being inexperienced, any decent person will understand! :)
I've heard that practicing on a large doll is a good way. I didn't use one. I had fun figuring that out as my relationship went on. As for big, wet ones... The first time I was French-kissed by someone, I hit him. It was his idea (at the time I'd only heard about it), which I thought was rather forward of him because I'd not known him long. AND he had a dip in his cheek. He got the taste of chewing tobacco, bits of it, included when he stuck his tongue in my mouth. I neither smoked nor dipped when I was younger (I don't do either now), so his little surprise was a nasty one. To this day the idea of big, wet kisses reminds me of that date at the fair. As for my date, himself, I heard that, when I hit him, he'd swallowed his dip and he was sick as a dog later. I didn't see it. I'd used my 'mad money' (and I was mad, too)to call home and my mother came and picked me up. What I'm saying is don't rush things. That may very well be something that that very special someone and you will like to learn about on your own. When it happens, you'll get all the practice you need.
