Every Dog Has His Day (Or Night)

Out to most people,he is capable of being discreet when needed;though most of his friends are gay,he is also comfortable with those that are not.He has tried life with another man(a semi-monogamous relationship with a sweetheart from college),but now he is sucessful and happy just being single.He hooks up sporadically depending on his mood and work load and maybe even the shape of the moon.
