Well, timing yourself while masturbating would probably make it last longer because you aren't as into the sensations.
What is 'normal' for one person may not be normal for another.
I am going out on a limb and suggesting that maybe he isn't allowing himself to be full involved in the moment. It sounds like he is either concentrating on too many things or easily distracted or a combination of the two.
Another factor might be how aroused is he is. How much time was spent on foreplay?
