Can you explain your situation a little more?
Did you know he was 14?
It is an indecent image so viewing it would be an offence anywhere in the UK.
If you didn't view it though then it would not.
It depends what you have actually done.
There is no defence in saying that the event itself took place in the Phillipines though.
Can I clarify anything for you?
What was your immediate response when this was offered?
Yes, but did you know that you were being offered an indecent image when you negotiated prices?
If you haven't watched anything or negotiated anything then that is not an offence.
I'm happy to continue with this please rate my answer.
