(CBS/AP) BELLEFONTE, Pa. - The first witness in Jerry Sandusky's trial said the former Penn State assistant football coach sexually abused him as a young teenager on campus and in hotels and later sent him "creepy love letters."
The witness, dubbed Victim No. 4 by prosecutors, said what began as "soap battles" in the shower escalated into inappropriate touching and oral sex. He said under cross-examination that he feels responsible for what happened to other alleged victims because he didn't come forward earlier.
The man, now 28, was the first of eight alleged victims expected to testify during the trial, which began Monday with opening statements.
Sandusky faces 52 criminal counts that he sexually abused 10 boys over 15 years, allegations he has denied. His arrest and the fallout led to departures of longtime football coach Joe Paterno and the university president.
The trial is expected to last several weeks. CBS News' Armen Keteyian reports that Sandusky's attorney says Sandusky will testify in his own defense.
Lead prosecutor Joseph McGettigan III opened Sandusky's highly anticipated trial Monday by telling jurors that the 68-year-old retired coach was a pedophile who took advantage of fatherless children or those with unstable home lives, plied them with gifts and sexually abused them for years.
Defense lawyer Joseph Amendola countered that some of the alleged victims had hired civil lawyers and had a financial interest in pursuing the criminal case.
Sandusky sat still as the first witness explained that he began showering with the former assistant coach in 1997, when he would have been about 13 years old. The man said he had met Sandusky through The Second Mile, the children's charity the assistant coach had founded.
The witness spoke calmly and firmly when questioned by McGettigan. Wearing a white shirt, dark tie and dark pants, he looked straight ahead at McGettigan during questioning. He gestured at times when asked to describe interactions with Sandusky.
"He would put his hand on my leg, basically like I was his girlfriend ... it freaked me out extremely bad," the man said, extending his right arm out and pushing it back and forth.
"I pushed it away ... after a little while, it would come right back. That drove me nuts," he said.
Instances in the shower, the man testified, escalated to the point where either Sandusky maneuvered himself so his head would be near the boy's genitals, or vice versa. The man testified that there were "a few occasions" where Sandusky ejaculated in the Penn State locker room showers.
Pictures of Sandusky and the then-boy were shown at times on a video screen. The man was asked to identify photos handed to him by McGettigan, including those with Penn State football players, but rarely looked over when the pictures were displayed on a screen large enough for jurors to see.
A self-described college football fan, the man said he enjoyed the access to Penn State football games and facilities. At one point, the man said, Sandusky let him wear the No. 11 uniform of LaVar Arrington. Prosecutors also showed a picture of the man, as a boy, with Arrington.
The alleged victim said that he even though he weighed barely 100 pounds at the time, Sandusky led him to believe he had a shot to eventually earn a spot on the Penn State football team, CBS News' Josh Gaynor reports.
"I still believed maybe I'd be a wide receiver or field goal kicker," the man said.
The man testified that Sandusky also took him to bowl trips including the Outback and Alamo bowls. He also gave him golf clubs, snowboards, drum sets and various Penn state memorabilia including a watch from the Orange Bowl, the man testified. He said he would wear gift jerseys to school.
The man said he stayed either at his mother's or grandmother's home at times. He never told his grandmother.
"No, no way. I was too scared to ... The other things were nice. I didn't want to lose that," he testified.
The witness said that, as he got older and after he got a girlfriend, he was "basically getting sick about what was happening to me."
He testified to one alleged interaction before a bowl game banquet in Texas, in a hotel bathroom before taking a shower, that Sandusky pushed down on him in a "downward motion."
The man said he resisted, when he testified that Sandusky responded, "You don't want to go back (home), do you?"
Asked by McGettigan to clarify, the man said "that he was trying to get me to have oral sex, and threatening me if not."
He said about 10 seconds later, Sandusky's wife, Dottie, called out from another room, and that an apparently surprised Sandusky left the bathroom.
Sandusky also sent the man letters, he testified. One shown briefly on a video screen in court was a handwritten on Penn State letterhead, signed "Jerry"
"I know that I have made my share of mistakes," the letter read. "However I hope that I will be able to say that I cared. There has been love in my heart."
The man described some of the correspondence as "creepy love letters ... Others would be, `Hey, do you want to come to a football game?' Those kinds of things."
Under cross-examination, the man said he was reluctant to cooperate with the investigation into Sandusky. He also said he had spent years "burying this in the back of my head."
"I thought I was the only person," he said. "I just came to terms with that and just wanted to go away."
Amendola also asked the man why he wasn't more forceful in shunning Sandusky earlier, and the witness replied that he didn't want to raise suspicion that might result if he cut ties suddenly.
He also expressed remorse, saying, "I feel if I just said something back then ... I feel responsible for what happened to other victims."
Amendola also pointed to a series of behavior contracts signed by both the witness and Sandusky. One such contract promised the witness money for post-high school education in exchange for participating in soccer, hockey, golf, as well getting grades no lower than a C and having no suspensions.
"Clearly this is a contract for me to be around him more often. There's even a part in there for me to come over to exercise with him three times a week," the man said, shrugging his shoulders.
