How to tell a girl that you want only to stay as friends?

You're entirely off on 'cuddling'. Cuddling can be done if two people are not dating, friends can do that. At least, it's pretty damn normal here. I cuddled with a couple of girls that were close friends, but we're not dating. Also, when you meant 'sleeping', instinctively, my reaction was of course 'intercourse', so I responded in the sense that you meant so. Cuddling is basically the same as hugging, except it's a prolonged sense of satisfaction and love. I only think kissing mouth-to-mouth or at times, mouth-to-cheek usually means a sign of dating or relationships (serious or not).
