16 or higher, yes. But, the age gap shouldn't be too big at that age as well. My personal opinion, 10 years at that age, max. Anything above 25, add whatever age gap you wan't, they are adults in the true meaning of the word.
Is it possible that you are thinking that, because age of consent is very high in your country?
Hm... maybe. After all, I was raised that way.
But still, I've seen how much teenagers at that age have going on up there, they're just thrill seekers at that age, they really don't know anything about life, they could easilly be fooled by someone older than them.
