Brooke Shields ran out after losing virginity to Dean Cain

Brooke Shields felt “regret” after losing her virginity to Dean Cain.

In her “Pretty Baby: Brooke Shields” documentary, now streaming on Hulu, the actress recalls running “butt naked” from the room after being intimate with the “Superman” star nearly 40 years ago.

Shields remembers Cain being “more comfortable with … the sexual part” of their romance.

“I wanted to jump into the personal relationship and the love and the commitment,” she explains to viewers. “We had to teach each other about each other.”

Although the “Suddenly Susan” star did not initially understand her reaction to having sex, she now knows she felt “sort of a regret for lost exploration and opportunity to understand my personal sexuality.”

She adds, “I feel bad for that girl. She was old enough to own her own body for real. And … just I couldn’t get there at that moment.”

Prior to her and Cain’s hookup, Shields was sexualized as a child star.

The “Blue Lagoon” star describes the “regret” she felt.

She played a prostitute in the 1978 movie “Pretty Baby” at age 11 and appeared in nude scenes in “The Blue Lagoon” three years later, which she has since said “would not be allowed” now.

The model was infamously dubbed “the most famous virgin in the world” when she wrote in her “On Your Own” memoir in 1985 that she had yet to do the deed — a disclosure she later regretted.

“It was, in hindsight, a bit of a mistake for me to be so open about my virginity because it never left me alone,” she told “Now What? With Brooke Shields” podcast listeners in November 2022.

In addition to receiving “fan mail from kids” asking her advice on having sex with their partners, Shields was also bombarded with “creepy” questions from men.

“To be in the line of fire at such a young age in that way, I gained a resilience, and it set me up to be ready for anything in this industry, which can be difficult,” she said.

Shields’ daughters — Rowan, 19, and Grier, 16 — didn’t realize the documentary would cover hardships they “did not know about.”

“I got in trouble with them … because they were mad that I didn’t inform them about everything,” the “Lipstick Jungle” alum told People earlier this month. “But needless to say, it opened up some other conversations.”
