25-year-old Zac Efron had a nervous time shooing for a sex scene in his upcoming film At Any Price, opposite co-star Heather Graham.

Having been a fan of Graham and revealing to have had a crush on her, Efron says that as it was his first sex scene ever, he was pretty nervous and besides he wanted to get it right with Graham, who he believes is the epitome of that perfect girl.

On the other hand, Graham found it funny hearing that he was nervous and says suddenly she felt like an expert when she also got to know that it was the first time director Ramin Bahrani was shooting for such a scene.
