The third came from his increasing interest in exhibitionism, a kink initially kept secret, until an incident in high school, several months before his graduation, involving the Roosevelt Raiders lacrosse team, and the Roosevelt Barnstormers girls volleyball team, broke open both the third and a fourth issue, which ultimately would characterize a crucial part of his personality.
To put the incident in perspective, Matt's academic schedule set him apart from his classmates, and the fact he took few gym classes meant few saw him in that context.
Matt, as such, became the focus of considerable resentment from students and a few teachers, including the team coaches, who felt he was given special privileges, distinct from his classmates.
Such resentment provided, in part, the fuel for the prank-infused bullying; a source of annoyance to the young nerd.
Moreover, his style of dress, intellect, and general open, friendly, but awkward personality, led many to make assumptions about his physical appearance.
None had never seen Matt at a pool, or unclothed, and he tended to wear baggy sweatpants and shirts while exercising.
The day of the shattered assumptions saw Matt performing his usual routine in the high school gym.
The Raiders had just finished their post practice shower, while the Barnstormers were filing in for their own.
Coaches and managers for both teams were present. Several faculty were in the gym for an impromptu meeting regarding the upcoming prom.
Matt finished his workout and went to the showers, not noticing the hostile glances of some of the lacrosse team (it should be noted the hostile looks were shared by the team coach, who held a strong contempt for nerds).
The looks turned to malicious mischief, and several players, one known to be a very good lock picker, re-entered the showers, emerging a few moments later with Matt's clothes and towel.
Giggles and laughter spread among the lacrosse team, and later the volleyball team once the girls heard the news.
The prospect of Matt the Nerd, humiliated, and shuffling nude out of the showers, once he found his clothes missing, was an attractive prospect to many.
More than a few among the lacrosse and volleyball teams held assumptions about his "measuring stick" and bets flew among the players as to its, presumably, tiny size.
There was even a short-lived contest for the new nickname to be bestowed upon Matt when the "big" (id est, little) reveal occurred.
The teachers and coaches present either didn't notice or (and it was considered more likely) made a show of ignorance.
In any case, moments later, the teachers most definitely noticed. So did everyone else. The Raiders and Barnstormers received a very stark lesson on the mistake of making assumptions.
The vision of Matt Frankenheimer (later to be referred to as "Schwankenheimer" "Frankenhammer" "Monster Matt" take your pick) striding bold, nude, and wet, wearing just his glasses and an annoyed scowl, out of the showers and into the gym, was not what silenced the laughter (albeit the lack of embarrassment on his face played a role as well).
It was the revelation Matt's body was cut like a Greek statue, and he sported a cock that would make the top gay male porn stars castrate themselves with envy.
Matt, ignoring the lacrosse team, strode instead to the coach, who watched with stunned open jaw.
"My clothes are gone, sir. One of your team has my clothes."
The coach said nothing.
Matt stepped forward. The coach stepped back.
"I would like my clothes back, sir."
The coach blinked, then turned to the Raiders. "Ahem! Wh-Which one of you maggots have Matt Frankenheimer's clothes! Step up! Give them back or everyone pays for it!"
Matt got his clothes back.
His return to the lockers also allowed everyone a view of his sculpted bubble butt.
Silence reigned over the gym. A mysterious individual (one of the teachers, so the rumor went), whispered, "Holy Fuck!"
In the shower, before he put on his clothes, Matt masturbated. The incident revealed certain things to himself, which effectively changed his relationship to others.
One: people seeing him naked turned Matt on. Two: his nudity could be a force for intimidation, and he liked that power.
Matt was a nice guy but, in that moment, he realized he had some teeth. All it took was not to wear anything.
Matt's dating prospects changed drastically after that day. He found his locker stuffed with phone numbers. The newly acquired nicknames were whispered behind his back, in non-derisive tones. Girls, and a few boys, began to come on to him.
Matt, initially, opted not to take advantage of the extra attention; not so much from shyness, as his displeasure over the incident.
Matt was a young man who put great stock in a person's character (a credit to the values Simon and Bette instilled in him).
Most of those showing interest had teased and bullied him, and his fellow geeks, across the preceding years, leading to a reluctance to engage with any of them.
Matt's ability to speak candidly with his father about these new developments testified to the good, close relationship they enjoyed.
Simon gave advice on being careful about his relationships; Matt could have fun of course but should also take care to distance himself should flaws in character become apparent. He assured his son of his own faith in Matt's judgment.
Discretion was another value he taught Matt. "Not everybody will accept your lifestyle, son. I learned that myself when I was your age."
He advised his son on the right times when, and venues where, he could display his body.
"Don't use your nudity to intimidate, unless you absolutely have to," he said. "Nudity can be invasive to some people, and only the worst type of men force it. I didn't raise you that way, and think about your mother and sisters. You don't want to disappoint them either."
"Yes, sir."
Simon gave his son a list of nude resorts and beaches he, himself, frequented.
"There are places where you can hike and stroll around in the nude too. And if your mother, sisters, and I aren't around, do what you want. If people see you in the backyard, so what? They're looking into your private space, not the other way around."
Matt lost his virginity to Cynthia Briggs, leader of the Roosevelt Royals Cheer Squad, a few days after his chat with Simon.
He did surprisingly well his first time. Unfortunately Cynthia's character turned out not to be up to standard.
The whole affair was for bragging rights to be the first to deflower him. Plus, she wanted to make her boyfriend, Joey "Jug" Bradford, captain of the Roosevelt Rangers Football Team, jealous.
Cynthia also got off on the potential violence Jug would unleash.
The couple didn't take into account Matt's self defense skills.
Jug had to miss a couple of games afterwards. Cynthia's relationship, and her social life, received no benefit.
Matt slept with his first older woman a month after Cynthia. Melanie Thompson, the math teacher, and hot milf, invited Matt to her house, to discuss a mistake he discovered in the math textbook.
He came to her house with the book, expecting a talk on a possible misprint. She met him in the kitchen, in nothing but a smile and suntan oil.
It was a gamble on her part but she guessed correctly. They didn't talk about the math problem.
The (secret) relationship actually continued past graduation, but he asked that someone else evaluate his math grade.
The sex was great, and the relationship open. Melanie proved an excellent teacher in carnal activities.
News of the gym shower incident also spread around the neighborhood. Part of it was attributed to the more stiff-necked members of the faculty, and the principal, who attempted to suspend him over the affair.
Simon and his lawyer shut it down, after they pointed out the clothes theft was the latest in a series of bullying incidents. In spite of complaints by Simon and Bette, the incidents were dismissed by the principal and faculty. The Frankenheimers had greater grounds for a lawsuit, than the school for suspension.
Matt would find many opportunities to help the local housewives with their household chores (while the husbands were away, of course), along with assisting their daughters, and in a few cases, sons, with their homework.
His last months in school, and before college, would see his sex life increase exponentially.
Matt would sleep with his first college man, a quarter into his freshman year. He eschewed the Greek life on his father's advice. Simon's bad experiences with bullying, obnoxious fratboys, during his college years, played a role in cautioning his son against fraternities.
Matt opted instead to share a dorm with an Engineering Major, two years ahead of him, named Patrick Bradford.
Patrick was tall, handsome, friendly, neat, and respected Matt's privacy. Matt, in turn, was discreet, not wanting to put off his roommate with his nudist activities.
Patrick kept a busy schedule, occupied with classes, work, and a girlfriend. Matt could indulge in his nudity often.
However, as inevitable, the roommate came home unexpectedly, from an excursion, causing a bit of awkwardness.
It lasted for just a few moments.
Matt found, in short manner, Patrick to be very open-minded, remarkably tolerant, very liberal in regards to sexual attitudes, complete with a colorful, adventurous, relationship with his girlfriend.
It took a couple of weeks to coax Matt into a threesome, which he enjoyed immensely.
The couple also made clear the new relationship was very open, allowing Matt to explore other territory with few complications.
