>I DON'T KNOW SPANISH!!
You don't have to, Camilo is not a spanish name (I think), ask him for more details on that
>Camilo does sound girlie in English...
Not to me... and, you know, most names in spanish have female and male versions (mine doesn't). For example, there's Fernando and there is Fernanda. Or Juan and Juana.
>I will call you Camille now, short for Camilo..
I don't think he would like that, you'd better ask him before start calling him differently.
