God is referred to in the Bible numerous times (both Hebrew/Aramaic and Greek, Old/New Testaments) as a "he", and "Father" as well as "Son" and "King", all masculine terms. God is not referenced in feminine terms any place I am aware of. Jesus, of course, is a man, not a woman, and is a historical figure and fully man and God.
As far as "understanding" Him, if you know the Son, you know the Father.
Personally I believe God is a spirit, and has no body, nor need for sexual organs. God is referred to as a father, for that is how God acts. God is referred to in masculine terms, because men were the ones writing. However, Jesus most definitely was male...I'll give you that.
