As a 16 year old boy out for a bit of fun you examined the options and smirked as you figured out how to break the machine. "Oh, this'll be interesting."
Even though you were a guy, the machine didn't disable the option to make your gender male. Curious as to what the effect would be you clicked it and waited to see what would happen next.
Curiously enough it seemed to be applying several packages at once, initially you looked to be getting older, but that was just the amplification of your male sexual traits. Your jaw widened and a 5 o'clock shadow appeared, your height increased and your shoulders broadened. Your form then began to fill out with muscle dropping you squarely into the athlete category. Looking carefully, you marveled that all together you looked like baby-faced 20 something but it was all just extra maleness shining through.
'Very nice, if only it were that easy.' you thought to yourself feeling hungry all of a sudden.
You stood up and clawed your way out of the machine not realizing how claustrophobic it was in there until now. Marveling at the pictures it generated you shoved them into your pocket accidentally brushing up against your penis which felt like you needed to readjust it.
