I think there's a big difference between the sweet kiss that shows you care, and the consuming type that hypes up your hormones and gets you reared for other things. The former one I believe leads to a stronger emotional, rather than sexual connection, which can be good for a relationship. But I guess it's sweet too if you wait until marriage. Just make sure not to miss with a lack of practice! (that's what happened to my friend on his first kiss....)
