How braces gave Dr. J a daughter

Page Six's Richard Johnson got ahold of Julius Erving upcoming memoir, Dr. J.

The excerpt he got is quite the doozy.

STEVEN M. FALK / STAFF PHOTOGRAPHER Julius Erving, a/k/a Doctor J, hit the red carpet Thursday at an art gala and auction benefiting the Mural Arts Program.

In the autobiography, Erving writes about the affair he had with sportswriter Stephanie Stevenson. Their union begat tennis star Alexandra Stevenson.

The good Dr. writes, "I can only remember one time that we actually had intercourse, and that was because she had just gotten this new orthodontia to straighten her teeth. With wire and gleaming metal bristling in her mouth, oral sex was not an option."

Well, then.

That's rather poetic, isn't it?

Dr. J hits stores Tuesday.
