Zac Efron insists he's in no rush to settle down and have children -- because the thought of becoming a dad frightens him.
The 21-year-old High School Musical star -- who is currently dating Vanessa Hudgens -- admits he's not ready for parenthood.
"The very idea of kids is frightening to me," he said. "Maybe it's over-exposure at a young age to a lot of kids.
"Right now I think I'm honestly, deep down, too selfish of a person. So I don't have that longing yet but I think eventually maybe it will come.
"I guess you take the necessary precautions. That was the advice that was given to me early on and I've always followed it."
Efron also insists he would never have sex with anyone he wasn't in love with -- but admits his attitude may change in future.
"I think everyone thinks that at some point -- it's just how soon you change your own opinions," he said.
