Ian Somerhalder Lost His Virginity At 13 - After Spying On His Big Brother Having Sex: 'He Taught Me A Lot'

Ian Somerhalder stopped by Andy Cohen’s SiriusXM show Radio Andy on Wednesday and freely spilled some tea of the teen sex flavor.

He revealed he lost his virginity at the tender age of 13 (!!!) when he was a young model.

Recalling his romp with the “older” 16-year-old girl, the Vampire Diaries alum said:

“[I was] 13. It was fun. When you’re 13 and you’re a boy, you know, or a girl, but boys are pretty on it.”

And in it, apparently! Ha!

The now-40-year-old attributes his early blossoming to the many long, cold nights he spent watching his big brother Robert, who is seven years Ian’s senior, performing the act with his lady friends.

Wait, what??

Admitting his big bro “taught [him] a lot” about sex, the actor recalled:

“He was quite a Casanova. He used to have girls in his bedroom all the time and what I did was, I went into the bottom corner of his window and I pinched the Venetian blinds. I pinched the blinds down so I’d have a clear view, and then when he’d have girls over — by the way, Louisiana gets cold in the wintertime, it’s freezing — I would go outside, put on all my stuff; my mom thought I was going out to play with the dog. I grabbed my hot chocolate, put on all my clothes, my mittens and stuff, and would watch, and I learned a lot!”

Ew!

Who would have thought future sex symbol Ian was such a little creep??

While some might find the act of spying on others having sex to be sketchy (and, you know, illegal), Ian insisted he was learning — not creeping — while watching Robert do the deed.

He continued:

“We do what we had to do. This was the live-action organic version [of internet porn]. Now, kids are watching all this s**t on the internet and it’s destroying society.”

Right. Porn. That’s the problem.

But in what may be some form of karmic retribution, Nikki Reed’s husband went on to admit he fears having to deal with gutter-minded boys (like himself) when his 2-year-old daughter Bodhi comes of age.

He noted how being a father to his daughter is “scary” due to his experiences as a teen, explaining:

“You look, like, at these little dudes [angrily]… It’s so vastly unfair. All my friends who are guys who have sons are like, ‘Yeah, you’re going to get a date, you’re gonna do this. While all the dads with daughters are like, ‘I will kill these little bastards.'”

Watch out for the 13-year-olds!
