Just when you thought maybe Megan Fox was sharing too much when she revealed that she’s bisexual, her “Transformers” co-star Shia LaBeouf has upped the ante.

Shia talked about his first time in a Playboy interview, and dashed every woman’s dream (mine only, I know) where he revealed that he’s not well-endowed.

He says, “I was shaking in my boots. Getting naked was very strange. It was the first time I’d been naked in the light, in front of a girl, with no hiding place.”

That’s when things got awkward for the star. He said that he tried copying a porn that he’d watched. He adds, “I remember putting a pillow underneath her because I had seen that in a porn movie…It put her at a weird angle, where I couldn’t get in correctly. I’m not extremely well-endowed…and clearly this wasn’t the move.”

He went on to say that the two of them dated for a while, where she taught him a couple of things. He says, “We had a lot of sex and would read the Kama Sutra together and do the wildest s**t.”

How’s Megan going to one-up that one?
