One could be a story about three friends, a man, a woman, and another man. They go on adventures together, sharing their different perspectives based on their genders and sexual orientations. There's mutual respect and understanding among them, and they support each other in their personal and professional lives without any sexual undertones.
There's a story where an MMF group works on a community project. M1 is good at planning, M2 is excellent at building, and F has great people skills. They come together to build a community garden. Along the way, they learn about each other's cultures and backgrounds, and they form a strong bond based on mutual respect and the common goal of creating something beautiful for the neighborhood.
One could be a story where two male friends and a female friend go on an adventure trip. The two men initially take the lead in decision - making during the journey, like choosing the routes and campsites. However, as the trip progresses, the female shows her intelligence and strength, gradually taking over some of the domination in terms of navigation and problem - solving. It's a story of friendship and mutual respect rather than anything inappropriate.
One alternative could be adventure - themed stories. These can involve a group of friends or a family going on an exciting journey, facing challenges and growing together. It's full of excitement and exploration.
Another example is 'Aristotle and Dante Discover the Secrets of the Universe' by Benjamin Alire Sáenz. It's a story about two boys who form a deep friendship. While not explicitly about bisexuality at first, as the story progresses, there are elements of complex sexual identity exploration in a very innocent and non - erotic manner.
An MMF story could be set in a post - apocalyptic world. M1 is a survivalist, M2 has medical knowledge, and F is a great scavenger. They team up to find a safe haven. Along the journey, they face threats from other survivors and harsh environmental conditions, and they must trust each other completely to survive.
Some modern YA novels also start to include bisexual characters in a more family - friendly way. For instance, 'Leah on the Offbeat' which is about a bisexual girl dealing with high school, friendship, and first love in a relatable and non - erotic manner.
