 The school bell rung; class was about to start. There was a knot in my stomach as I walked from the puzzle area, past the boys playing sports and girls knitting daisy chains. It was the day I'd heard about from the older kids - sex ed. There was a strange sort of adrenaline rush from the idea of talking about something so taboo. 
 
 From my knowledge of sex, I knew it involved a man and woman with a triman as an intermediate; but how the act worked was a mystery. I did n't even realise that only men had penises and only women had vaginas. 
 
 When I entered the class, we sat boy-girl-trine and waited for our teachers to arrive. After a few minutes of patient waiting, the class turned to chatter, boys talked of sport, girls of relationships and trines of maths and various puzzles. 
 
 Mr Dickinson, Mrs Muff and Mrss Johnson arrived through the door. The class hushed up, with the boys being the last to quieten. Mrss Johnson - who was wearing a fine green robe, stood at the front of the class and said in a nasally voice `` Today we will be having sex education, we will be splitting the class into three groups - boys with Mr Dickinson, girls with Mrs Muff and trines with me.'' 
 
 The male and female students left the classroom in single file lines with their respective teachers while the trines sat, ogling at the opposite genders. Mrss Johnson marked the start of the lesson by screeching chalk against the board writing `` Sex Ed''. 
 
 `` Now class'', he said articulately, `` Does anyone know anything about sex?'' 
 
 Almost everyone in their class put their hands up - including me. I had no real idea what sex was, I would just look like a stupid girl or boy if I had n't done. Alexander seemed lively to share his knowledge of sex; `` The man's willy goes inside the trine's vagina, where the sperm is activated and travels out of xe's penis into the woman's vagina to fertilise her!'' 
 
 Mrss Johnson raised an eyebrow. `` You are right, Alex - though I am slightly surprised you know that much'' he said, leaning over to get Alex a star shaped sticker. 
 
 `` Now, we're going to watch a short tape which should explain sex.'' Johnson said, inserting a tape dated 1955 into a dusty old projector. 
 
 The tape explained exactly what Alexander had said, however it added detail about how the addition of the triman's DNA to the male sperm allows the male sperm to fertilise a woman's egg. It showed an 2D cartoon of a triman penetrating a woman while being penetrated by a man. The tape then went on to explain the process of puberty in each gender; `` At aged 13 for a triman - puberty will begin. The triman will experience hair loss until they are completely bare of any body hair except for eyebrows. They will also experience an increase in the size of their activation glands next to their penis.'' 
 
 During puberty, a triman will start to become interested and aroused by the opposite genders - this is a completely normal and natural experience, so do not be worried if you feel this way about people. However, if you are aroused by the presence of a single member of the opposite gender; you may be a duosexual. While having duosexual thoughts is not illegal, engaging in sex with a single other partner is a sinful crime which can result in prison time or chemical castration.'' 
 
 When the tape was over, the whole class was taking notes. I wondered what the girls and boys were thinking; I imagined that they would have been disgusted or shocked, but us trines see things differently. The revelation of sex was merely a new snippet of information. It made everything about the world seemingly fit together like a hand in the glove; men had sex with trimen and trimen had sex with women. Us trimen were the middle ground, like with everything. We dealt with the emotional side of women and the aggressive side of men and that's because we facilitate reproduction between the two.
