Lehane, now 18, felt the same way after she heard the Republican presidential candidate bragging about groping women without their permission. The first man had sped away before she could muster a response. This time, the teenager said, she had two days to prepare a comeback. She found a white T-shirt and bought some black iron-on letters. She showed up at the Donald Trump rally Monday wearing a message: Grab my p---y. I dare you.

The 2005 tape hit the Web Friday, launching a national conversation about how society treats women. The footage shows Donald Trump, then 59, chatting with former “Access Hollywood” host Billy Bush. “You know I’m automatically attracted to beautiful — I just start kissing them,” the GOP nominee says in the recording. “It’s like a magnet. Just kiss. I don’t even wait. And when you’re a star, they let you do it. You can do anything.”

“Grab ’em by the p---y,” Trump says. “You can do anything.”

The White House said Trump was describing sexual assault. A surge of Republicans also condemned the candidate, some calling for him to drop out of the race. Canadian writer Kelly Oxford asked women on Twitter to share their assault stories, writing, “I'll go first: Old man on city bus grabs my 'p---y' and smiles at me, I'm 12.”

Lehane, a high school senior, thought about the men who’ve leered at her. Some classmates. More strangers. “It makes you feel out of control,” she told The Post. “Like you can't make them see you're a person.”

Middle and high school girls tend to experience more sexual harassment than their male peers, according to a 2011 study by the American Association of University Women. The survey found 56 percent of girls and 40 percent of boys reported being the target of unwelcome sexual remarks. Girls were much more likely than boys to say such treatment affected their ability to sleep and their desire to leave the house.

One finding cut against the general belief that boys tease or toss suggestive remarks at their crushes. The survey asked students who admitted to harassing others why the did it. Only 3 percent said “because I liked them,” while 44 percent said they felt such behavior was “not a big deal” and 39 percent said they were trying to be funny.

Even sexual assault starts early. The Justice Department defines it as “any type of sexual contact or behavior that occurs without the explicit consent of the recipient.” Forty-four percent of reported assaults take place before the victim is 18.

After the tape surfaced, NBC suspended Bush from the “Today” show. Trump apologized for offending people, dismissed the remarks as “locker room talk” and kept campaigning. He arrived Monday in Lehane's community, pledging to grow jobs in Pennsylvania and imprison his opponent, Hillary Clinton.

The teenager, who initially backed Bernie Sanders and now supports Clinton, wasn't sure what to expect as she moved through the crowd. She spotted a man sporting a shirt that said, “She's a c---t. Vote for Trump!” She noticed people staring at her, but not necessarily in a mean way. One guy, wearing a “Make America Great Again” hat, complimented her outfit. Another called her a “commie.”

Lehane had heard about scuffles erupting at Trump rallies nationwide. One had ended with a man getting punched in the face. She wasn't nervous, though. Not with a trio of reinforcements. They also wore homemade shirts. Theirs said “Black lives matter.”

At one point, a police officer told them he'd kick out noisy protesters. But the high schoolers didn't plan on talking to anyone. They preferred a silent statement. Then came a man who looked like a grandfather.

“I always like a good dare,” Lehane recalls him saying.

“That's assault,” she replied.

He turned away.
