16, 17 depending on the kid. Some are a lot more mature than others....some are too mature nowadays. I wasnt ready till I was 18 and even then I wasnt looking for anything at all serious.
I think fourteen/fifteen is a good age for dating to start. I would keep a really close rein on the dating at that age though. Once they hit sixteen I would loosen up a little bit, but not too much.

Finding my muse
Hmm I think it depends on the person & what date they are going on.. Sensible dates like the cinema with a curfew I would say are ok from about 14-15 x
