Confusion after the date

Jon walked into his house, confused from the date. He had enjoyed the movie, but wasn't sure how he felt about touching Kevin's penis. Part of his was excited to have a sexual experience, but part of him felt he should have touched a girl's parts, not a boy's parts. He made it was to the kitchen and opened the fridge door when his mom came in. She saw what he was wearing and did a doubletake and took a deep breath before she asked, "How'd it go?"
"What go?" asked Jon as he put down the gallon of milk he had just drank out of.
"The date, your new friend Sarah told me you were going out to a movie."
"Right, that. The movie was good."
"Anything else you want to tell me?" asked Jon's mom looking him up and down. Jon all of a sudden remembered what he was wearing.
"Sarah lent me some of her clothing. I'm going to get it off soon. I'd rather be in my usual shorts," said Jon walking off.
"Well I think the outfit looks cute. Your hair looks nice too. Was Kevin at least nice?"
"...How'd you know it was with Kevin?"
"Sarah told me when she dropped off the clothing she got for you."
"Kevin was fine. I'm not sure if I'll go out with him again though," said Jon
"Why?"
"Because I don't know how I feel about him. I'm a guy, he's a guy..."
"Nothing wrong with that Jon. Just think about it."
Jon turned around and went upstairs. He took off the skirt, pink shirt and shoes and put them into the bags that Sarah bought. He took the bags and to put them in the back of the closet, wondering if he could sell it all on Craigslist. He saw a few schoolgirl outfits in his otherwise male closet.
He put on his shorts, feeling relieved that he was in boy clothing, the girl clothing was very...tight.
He went over to his mirror. He saw a young boy with long blond hair. He locked his door and took off all his clothing and went back to the mirror. A very young boy, or maybe a young girl? No wonder Kevin thought he was Jen. It was all downhill after he wished to not have an erection in gym class.
"I wish I didn't have an erection in gym class for a different reason!"
His mom heard the wish and thought for a bit.
