He's a tosser
What N2L said...

I don't see a problem with it, at any age... Why is it that girls should only have girl friends and boys the same? It's silly...

Me best friend was male, we slept at each others houses for years... And my parents were fine with it (as were his) as we were just that friends... I don't see the need to discriminate over sex. And come to think of it A lot of my guy friends from when I was in primary school up until high school stayed over.
