In my experience, the desire to cuddle, once fulfilled, is quickly amplified and changed into other urges. That's how the species perpetuates itself.

Exactly. For guys (can't speak for the ladies) cuddling a slow form of foreplay. Doesn't necessarily lead to anything, but it's still foreplay.
When I was a kid, they had cuddling without foreplay all the time. It was called "dating." That was before "dating" meant you were continuing to court someone you had already had meaningless sexual contact with numerous times.
