Homosexuality
After his contact with IA over the strike team's theft of cocaine, Vic Mackey caught Julien in a homosexual encounter with a small time hustler named Tomas Motyashik. When Julien said that he would deny the incident, Vic smiled sadistically and said,
"I don't have to prove you're gay. In this house, all I have to do is say it with all the gory details!"
A terrified Julien reluctantly agreed to recant his story. Mackey afterwards exhibited friendlier behavior towards him, but Lowe never entirely trusted him.
Later, Julien asked his pastor, "What do you do if the man you are isn't the man you want to be?" The pastor retorted, "That's easy. Just give the man you are a good kick in the ass."
Julien's homosexuality placed him at great odds with his devout Christian beliefs, even to the point that he chose not to wear his vest to a bust, hoping the perp would kill him. Through his pastor, however, he eventually went through conversion therapy at his church and married the mother of a young boy caught spraying gang graffiti. Tomas was eventually arrested and when Julien refused to continue their relationship, he outed him to the entire precinct. Two officers tormented him over his sexuality and when they were later fired, they gave Julien a "blanket party," seriously injuring him. He later confronted one of the officers and broke his arm in retaliation.
Danny was once called to his house after his wife's son called the police due to a domestic between Julien and the boy's mother, which turned out to be a verbal argument. The argument stemmed from their frustration over their inability to have a child together. Julien went to get his sperm checked but the results were never shown.
When Juilen goes to a sperm bank to deposit his sperm as part of a medical procedure to get his wife pregnant, he uses a gay porn magazine as masturbation material.
At the end of the series Julien looks longingly at a gay couple, indicating stirring desires that haven't gone away.
