Age verifications

Hello dear Danes!

I'm desperately trying to find the answer to a question that doesn't seem to be googlable for a foreigner and I'm hoping one of you can help me out.

Under Danish law, do websites containing adult content require an effective age verification, aka more than a disclaimer with an enter button, saying "Yes, I'm an adult"?

I've been searching for an answer to this question for the last 2 days, this is my last attempt to finding an answer^^"

Thanks,

exec
