Danielle Fishel is known for starring as Topanga on the beloved '90s sitcom "Boy Meets World," a show she began appearing on when she was just 12 years old.

She spent the next seven years growing up on television and, as she's revealing now, there were some alarming interactions behind the scenes.

On "Pod Meets World," a podcast she shares with "Boy Meets World" alums Rider Strong and Will Friedle, a question came up about how they dealt with being seen as teen heartthrobs. While Strong and Friedle recalled feeling uncomfortable with all the attention from their female peers, Fishel's story was a bit different.

Instead of fellow teenagers giving her compliments or seeking her attention, she remembered adults telling her that they'd marked her 18th birthday down on their calendar or that they had photos of her in their bedroom.

"As a kid, I always wanted to be older. I always wanted to be an adult, I wanted to be seen as an adult and so getting adult male attention as a teenage girl… I didn't think of it as being creepy or weird," she admitted.

"It felt like it was validation that I was mature and I was an adult and I was capable and that they were seeing me the way I was, not for the number on a page. And in hindsight, that is absolutely wrong."

Fishel acknowledged that while she was always confident in speaking with adults, "in a romantic, male gaze sense I should not have been outwardly talked about at 14, 15, 16 years old."

"Even directly to me," she went on, "I had people tell me they had my 18th birthday on their calendar. I had a male executive, I did a calendar at 16, and he specifically told me he had a certain calendar month in his bedroom."

At the time, she didn't think much of it, explaining, "My first thought was a little bit like ‘oh.’ but the immediate thought after that was, ‘Yes, because we are peers and this is how you relate to peers.’"

Strong and Friedle also recalled having guest stars on the show, who were teenagers, and hearing older men working behind the scenes talking about how hot they were and about how the skirts for their costumes needed to be shorter.

They discussed how film sets were different working environments in many ways, that lots of physical affection had always been the norm, and it wasn't uncommon to walk into work and see a child sitting on the lap of an adult.

While they agreed that it wasn't overtly sexual, it wasn't appropriate either, and it likely wouldn't have been tolerated in other workplaces.

Fishel admitted that for years after these experiences she struggled with forming proper boundaries in relationships, letting things slide that she perhaps shouldn't have because she didn't want anyone to think that she believed she was better than them.

It wasn't until her late 30s – she's now 42 – that she realized there was a connection between those strange experiences from "Boy Meets World" and how she related to people in the years after the show ended.
