Monica Lewinsky said Thursday that her "issues" with "unavailable men" started in childhood.

"Looks like i had issues w/ unavailable men from an early age," Lewinsky said in an Instagram post alongside fictional characters Snoopy and Bert from "Sesame Street."

Lewinsky was involved in an affair with former President Bill Clinton beginning in 1995 when she was a White House intern. She was 22 when the affair began, and Clinton was 49.

Clinton was impeached in 1998, but was acquitted by the U.S. Senate with five Republicans joining Democrats in supporting the acquittal.

Lewinsky has struggled to move on from the scandal, and produced a documentary in 2021 titled "15 Minutes of Shame."

"One of the factors — and we do take people through this in the film — is around the idea of how shame had been used since the beginning of time as a social tool. When the printing press was invented, it all of the sudden leap-frogged into being something that could not be commoditized," Lewinski said in October 2021.
