Shipe was so traumatized that she had a car accident returning home from the party and never went to the police. In fact, for 12 years, she never told a soul, not even her parents.
"For six months, I couldn't even say the word rape," said Shipe, now 34 and a senior creative producer for Starbucks in Seattle. "I felt so ashamed. I completely shut down."
Shipe found a way to escape her dark secret at the university, where she was a stellar student and graduated in 2000.
"Penn State saved me," she said. "I worked my butt off to succeed and prove I was worth something."
But when she learned assistant football coach Jerry Sandusky had molested numerous young boys and for years no one had spoken out -- it unearthed all the deep scars she had silently carried.
"When Sandusky's story hit, it really rocked me," said Shipe. "It was an unexpected trigger."
She said the case opened her eyes and she not only sought counseling, but became an advocate for the Rape, Abuse and Incest National Network.
In October, Sandusky was sentenced to 30 to 60 years in prison on 45 counts of sexual assault against young boys.
Since that highly publicized trial, advocates say attitudes toward sexual violence have changed -- for the better. Visits to RAINN's National Sexual Assault Online Hotline are up 47 percent, and survivors like Shipe say they feel more sympathy and support.
RAINN now gets about 4,000 visits a month to its hotline from both men and women. And in the past year, supporters like Shipe have raised $548,000 to fund help for 13,047 survivors.
"The numbers are staggering," said Scott Berkowitz, founder and president of RAINN. "One of the interesting things about the Sandusky case it that its half life was much longer than a typical story."
"It really hit home with the public," he said. "There was such a volume of evidence from the beginning that his guilt was pretty clear in people's minds. And the victims were kids, so it resonated more."
According to RAINN, one out of every six American women -- more than 17 million -- has been the victim of an attempted or completed rape in her lifetime. Men are also victims: one in 33 have experienced sexual assault.
Children are particularly vulnerable: 80 percent of all sexual assault and rape victims are under the age of 30, but 15 percent under the age of 12. And in all categories and genders, most crimes go unreported.
Gregg Milligan survived rape and incest at the hands of his own mother. An alcoholic and a prostitute, she brought strange men home and invited them to abuse him.
The 49-year-old computer engineer from Michigan said the Sandusky case put violence against males into the limelight.
"In the past, [male victims] were very guarded," he said. "It floors many to think about the unthinkable. Very few males speak out because they are under a veil of shame."
"I know how difficult it is to come forward," said Milligan, who has six living siblings and wrote the self-published memoir about his abuse and recovery, "A Beautiful World."
"Even today, members of my own family have yet to admit the abuse took place and some have gone so far as to disown me," he said. "That's one of the many ugly truths about abuse -- it has a very powerful ally, and that's ignorance."
