I talk a lot about the Goddess aspects of Deity, but rarely mention the God aspects. Here are some of my favorite male Deities:
Mercury: Also known as Hermes, Thoth and a few other names, he is about knowledge. He also is a protector of thieves, and since I deal with troubled teens he looks after them in this aspect. He is also a messenger and is also a fertility God.
Libera: Known as the Green Man or Dionysus to some people, this deity is the male form of nature and also fun. He is a well known fertility God and also of wine and spirits. But he is also down to Earth and deals well with humans.
Saturn: This God gets a lot of flack because of the myth stories of him eating his offspring. He was risen in his father God status in Rome, and is considered a God of Plenty. Many others are aspects of this, but he is shown as a kindly old man protecting children. There is some research indicating Saturn is a prototype for Santa Clause (don't tell Christians that one) as he did give out gifts to deserving and poor children. He also is shown with a cornucopia of items. Saturnalia did become what Christmas is today and December 25th was Saturn's feast day.
Neptune: I do love the sea and everything related to it. I look at Neptune as representing the wrath and calm of the sea at the same time.
