Before I start, I want to make it clear that I don't believe G-d is male. Sex is a quality of the created world, part of the life/death cycle. Therefore, as G-d is not part of creation, the concept of sex does not apply. All three pronouns (he, she, it) express different aspects of G-d, but none encompasses G-d.
That said, the G-d of the Jews is understood primarily as a Creator who has shown an interest in how we treat one another, and who has revealed himself to as as the Lawgiver, that our behavior might be modified as to be above the animals. If a hamster does his mom, other hamsters don't care. If a human did his mom, it would rouse our conscience--in most cases. For those who don't "get it" that you don't do your mom, we make rules to clarify it with consequences to discourage it. Okay NOW I have to deal with some statistical generalities -- which means that the things I'm about to say will have plenty of exceptions. I'm strictly referring to the top of the bell shaped curve, so don't let it throw you. IF you examine male clergy, you find that in general they are more didactic, explaining to their congregations a better way to live. IF you examine female clergy, you find that their focus is helping individuals grow and creating harmony within the group. Both of these approaches are essentially good, despite their obvious differences. NOW, looking at those statistical generalizations, do you see why Jews primarily view the Lawgiving G-d as male? Oh, sure we are not limited to that personification--the Shekinah is a FEMININE noun indicating the localized presence of the omnipresent G-d. But if you understand that "He" simply refers to G-d's more masculine traits, and isn't actually stating that G-d is a male, it WORKS.
I truly hope this was helpful in a non-pushy way.
