When Ty first discovered his powers, he went wild but then he settled down because he learned from his experience.
First, Ty learned that he wasn't omnipotent. Although he could cause extreme transformations to the bodies and minds of people around him, he could not completely alter their identities. After vengefully messing with the lives of Dustin, Mark and June, they still didn't love Ty. So Ty got tired of vengeance. He restored the three of them to normal and then used his power to locate a family that would appreciate him more.
Second, Ty learned to appreciate himself and to stop comparing himself to others. Even after Ty finally became an adult, he was still average to small compared to others. He had used his powers to make himself bigger but he got tired of trying to be more than he was. He decided that average was just fine.
Third, Ty learned that even his magic was not his source of self worth. He had tried making friends by impressing people with his magic but found that they only wanted him for his magic. Those friends didn't appreciate Ty for being Ty so Ty stopped trying to impress people. He decided to just be himself.
When Ty started college, he was a calm and happy man. He made some new friends, guys that became his friends before he revealed to them his magic power. Ty still used his magic power because, if you got the power, why not use it, but Ty used his power without making a show so that most people had no idea that Ty had power. (Besides, Ty could cause people to forget if he didn't want them to know anymore.)
Ty also learned to appreciate his bisexuality. Although he wasn't actively pursuing any relationship of that type, he knew that he was attracted to both genders and he was okay with that. His best friend, Luke, was also comfortable with Ty's bisexuality.
Luke was an easy going guy. Luke didn't freak out when he learned about Ty's magic. He also didn't freak out when Ty admitted an attraction to Luke. Luke was hetero himself and was not attracted to Ty but Luke was comfortable about Ty's attraction. Luke was so comfortable that he let Ty see him naked and he let Ty touch him.
One day while Luke was visiting Ty's dorm room (which he had to himself and which he had magicked into a nice luxury dorm room) Luke said, "I'm bored. I wish you had a gaming system."
"I can have a gaming system whenever I want and I don't need money."
"Yea but how are you going to explain it so people don't realize you have magic?"
"I have plenty of experience using my magic without notice. How do you explain that I'm the only freshman who has a hot tub in my dorm room and no one thinks anything strange about it. Now strip."
Luke stripped without hesitation, "What are you going to do this time? Are you going to change me into your gaming system?"
"That's exactly what I'm going to do. Now put your cock in my hands."
Luke moved toward Ty and let Ty cup his genitals. Luke's flaccid cock began to harden.
"Your doing that to me. Your magic is turning me on cause you know I wouldn't get hard any other way."
"Do you care?"
"No, it feels good."
Luke's cock became longer, harder and plastic. Buttons appeared on his testicles which flattened out. Ty pulled and Luke's joystick came off with the button pad. The Luke's legs shrank and his torso widened into a giant, flat screen.
Ty stood up and stripped himself. Then he detached Luke's head and arms and reattached them to a chair.
"How am I going to play if you're using my cock as the controller?"
"Virtually. Just pretend you have a controller in your hands. Your mind is going to control the game anyway. You are the computer that I'm going to play against."
Then Ty detached Luke's ass and put that in the seat of the chair before sitting down in between Luke's arms.
"Hey, you're not planning on fucking me. I told you, I'm not into that."
"I know but may I rub my cock between your ass cheeks?"
"Alright but no cheating. So what game are we going to play?"
