Dekker has stated that for much of his childhood, he was a victim of sexual molestation. In his teenage years, he was part of a “metalhead” subculture, where he “caused trouble in Las Vegas”, and was arrested “five or six times”.
Dekker was involved in an auto accident on October 15, 2009, when he hit a 17-year old cyclist training for a race on a freeway onramp. Originally charged with two counts of felony DUI, the charge was reduced to one count of misdemeanor reckless driving when it was found that the cyclist was at fault. He pleaded no contest, and was sentenced to a fine of $300 and two years of informal probation, and ordered to attend a 12-hour alcohol-education class. Dekker is a vegan.
On April 20, 2011 in an interview with Out magazine Dekker spoke about his sexuality, which has been the subject of speculation. “I’ve only really had relationships with women, but I’m certainly not closed to it. If there are possibilities of being able to do anything in life, why would you say you would never take any up? In the later chunk of my teen years I was so all over the place with sex. It was terrible. I never really had a real relationship at all. During puberty, it’s all about sex, and it’s all about figuring yourself out. I think I overdid it when I was younger.”
