No. Since 'erotica' implies sexual or sensual content, mm erotica novels are not for all ages. They are designed for an adult audience who have a certain level of maturity and are interested in this specific genre. Minors lack the emotional and mental maturity to handle such adult - themed content.
I can't name any particular popular ones off - hand. However, in general, these novels might explore relationships between male characters in an erotic context. But it's important to note that they are not part of mainstream literature and are often restricted to adult - only areas due to their sexual content.
The height of MM in the comics isn't explicitly stated. Sometimes, such details are left to the imagination of the readers or might be revealed in later issues.
One real story could be a woman who was walking alone at night. A man approached her threateningly. She had a 9mm pistol for self - defence. She warned the attacker and when he didn't stop, she fired a warning shot into the air. The sound scared the attacker off.
Since I haven't read a work titled '9 mm pulp fiction' directly, it's hard to say for certain. However, 'pulp fiction' generally has a reputation for being fast - paced and filled with action - packed stories. The '9 mm' part could be a key element in the plot, like a 9 mm bullet being central to a crime or a mystery that the characters are trying to solve.
One of the best is 'The Lord of the Rings' series. It has a richly detailed fantasy world filled with different races and magic. The relationship between Frodo and Sam can be seen as a strong male - male bond within the context of a grand adventure. Another great one is 'A Song of Ice and Fire'. Although it has many storylines, the friendships and rivalries between male characters add depth to the story. Also, 'The Wheel of Time' is quite good. Male characters like Rand al'Thor go through incredible journeys and form important relationships with other male characters in this epic fantasy.
