Do u think that teenagers can look up porn on the internet

Yes, very easily.
ALL the major search engines make this a snip.

I KNOW they can. My cousins had plenty on their computers when we were growing up...

The op asked this same question on another board with the wording of 'should they be allowed to' instead of 'can'.

Can they? Yes.

Should they be allowed to? That should be a parental decision.

Hi, kingbig!

Why are you asking the question, please?

Thanks!
