In urging men not to masturbate, Pastor Mark Driscoll argues it's a form of homosexuality.

In a booklet titled Porn-Again Christian: A Frank Discussion on Pornography & Masturbation for God's Men, Driscoll of the Seattle-based Mars Hill Church suggests that the act could turn men gay.

“First, masturbation can be a form of homosexuality because it is a sexual act that does not involve a woman. If a man were to masturbate while engaged in other forms of sexual intimacy with his wife then he would not be doing so in a homosexual way. However, any man who does so without his wife in the room is bordering on homosexual activity, particularly if he's watching himself in a mirror and being turned on by his own male body.”

In sermons offered at this website, Driscoll also says that Christians should judge gay people like Jesus.

“If you leave this church, you can go to another church and they will tell you if you are living together and not married, that's okay. They'll tell you if you're gay, that's okay. They'll tell you if you're married and you're into porno and wife-swapping and open marriages, that's okay.”

“God is displeased with that conduct. …. Christians therefore must be judgmental like Jesus,” he adds, quoting the Apostle Paul.
