No. Writing and promoting erotic content, regardless of the gender combination, is not ethical. It goes against moral and social norms that promote healthy and respectful relationships.
To write men's erotic stories, men should be true to their own experiences if they are using them as a basis. But also, they need to be creative. They can take inspiration from art, music, or even nature. It's important to create a connection between the reader and the characters. The descriptions of the characters' feelings and actions should be detailed and nuanced. For instance, when describing a moment of attraction, don't just say 'he was attracted' but rather describe how his heart raced, his palms sweated, and his eyes were fixed on the other person. Also, they should consider the pacing of the story. A slow - building story can often be more alluring than a rushed one.
I'm not sure there are specifically defined 'erotic stories' in a mainstream sense for 'Mad Men'. The show mainly focused on the advertising world in the 1960s. It did have storylines about relationships and affairs, but not in a purely 'erotic story' way. It was more about the complex relationships between the characters, like Don Draper's many affairs which were more about his character's flaws and the social context of the time.
Well, it depends on the specific genre and the writer's intention. However, reducing a group like short men to just being in erotic stories in a certain way is inappropriate. Erotic literature should be more inclusive and diverse in character portrayal, not basing it on such physical traits.
There should not be any positive 'erotic' stories in a locker room. Locker rooms are places for people to change and should be about respect and privacy, not sexual undertones.
