Dean McDermott is many things:

Broke. Annoying. Desperate for attention.

But he’s also something else: A rather well-known cheater.

The reality star left wife Mary Jo Eustace for Tori Spelling — and then stepped out so many times on his second wife that he once checked into rehab for sex addiction.

(Editor’s Note: There is no such thing as sex addiction. Some lonely, insecure people may need companionship in some sort of pathological fashion… but one is addicted to the act of sex. That’s ridiculous.)

“I am truly sorry for the mistakes I have made and for the pain I’ve caused my family,” McDermott said in a statement in early 2014 after admitting to at least one affair.

He added at the time:

“I take full responsibility for my actions and have voluntarily checked myself into a treatment center to address some health and personal issues.

“I am grateful to be getting the help I need so I can become the husband and father my family deserves.”

That was way back then.

Now? McDermott is still largely known for the many affairs he’s carried out, a reputation he appears to have accepted long ago.

He can’t change it; nor can he change his part behavior, as much as he prays he could.

“I really, really wish that I had been given the knowledge of think with your head, not your penis, because I did a lot of thinking with my penis,” the 52-year-old confessed to co-hosts Adam Hunter and Nicky Paris on the first episode of the “Daddy Issues” podcast.

After Hunter and Paris spoke honestly about the guidance their respective parents provided them with over the years, McDermott said this wasn’t the case for him.

He that his dad didn’t really give him “any advice” at all, adding that he learned “how to be a man” on his own.

“I got three older sisters … lost my mother when I was 15, she passed away, and then Dad wasn’t around,” McDermott explained, crediting his son from his marriage to Eustace, Jack, for teaching him great deal.

“Having a kid the first time was what really taught me how to be a parent…

“As far as being a father, I sort of learned as I went along. … I made a lot of mistakes, but learned a lot. Six kids later, I’m still making mistakes.”

One shouldn’t need to have a stable upbringing to know that one should not sleep with someone who is not one’s spouse.

But fair enough, we suppose, Dean.

His marriage to Spelling has seemingly been on the verge of divorce ever since the stars got hitched in 2006.

Yet still, here they remain.

The two are the parents to many, many kids:

Liam, 12, Stella, 11, Hattie, 7, Finn, 6, and Beau, 2.

Back in December of 2013, Us Weekly broke the news that McDermott cheated on the Beverly Hills, 90210 actress with then 28-year-old Emily Goodhand while on location shooting Chopped Canada.

The couple documented the aftermath of the scandal for two seasons on Lifetime’s True Tori.

So at least they got some ratings and a few storylines out of the scandal.

And McDermott said on this podcast that the couple also grew closer after they overcome his unethical actions.

“It’s so not about the person you’re with,” McDermott said about cheating in general, concluding:

“For me, it wasn’t about [Tori]. It was about inadequacies in myself, I felt so bad about myself, I felt like a piece of sh-t, I needed to do that to feel some kind of power.

“It was horrible and I’m an asshole, piece of sh-t for doing it, [but now] our relationship is better than ever.

“That was a rough Christmas, we came out the other end.”
