No, they are not common. Penis exams are a private medical matter for most people regardless of sexual orientation. While there may be some stories shared within the gay community about general health exams that include penile examinations, it is not something that is widely talked about in public or mainstream media. It is more likely to be part of internal discussions within the community to promote sexual health awareness among gay men.
There are no such 'penis growth magic stories' in a real sense. Penis size is mainly determined by genetics, and while there are some medical and scientific ways to address concerns related to sexual health and development, there's no magic involved. Gay or straight, believing in unfounded'magic' for this is not based on fact.
The idea of 'gay magic penis growth stories' is rather absurd. Growth of the penis occurs through biological processes. It is influenced by factors such as proper nutrition during development, lack of certain medical conditions that could stunt growth, and normal hormonal balance. Tales that deviate from these scientific facts are more in the realm of fiction and should not be taken seriously.
In general, ancient literature was a medium to convey values, knowledge, and cultural heritage. It was highly regulated by the social and moral norms of that time. Stories about penis growth in an erotic context would go against those norms. For example, in Greek and Roman literature, which are among the most studied ancient literatures, we have stories of heroes, gods and their deeds, love in a more acceptable and non - explicit way, but not this kind of story.
This is clearly unethical. Encouraging someone to engage in sexual activities through erotic stories is a form of coercion. Everyone has the right to make their own decisions about their sexual orientation and sexual activities in a non - pressured environment. Such behavior violates personal boundaries and can cause psychological harm to the person being pressured.
There are no prevalent gay magic penis growing stories in mainstream mythology. Mythologies around the world are rich with various themes such as the origin of the world, the adventures of heroes, and the relationships between gods and mortals. The concept you mentioned is quite unusual and not a part of the traditional narrative in most mythologies. Even in stories that involve sexual or romantic elements, this particular concept is not present as far as I know.
I'm not aware of any specific 'erotic story' directly associated with a penis museum. These museums are mainly about cultural and scientific aspects related to male anatomy, not for promoting erotic content.
Yes, there are significant ethical concerns. Any form of non - consensual or harmful act towards the body, even in a fictional or so - called 'erotic' context, is unethical. It promotes violence and harm, and goes against the principles of respecting human dignity and safety.
We should focus on healthy and positive topics. For example, we can explore stories about love and friendship. Love stories can be about how two people meet, fall in love, and overcome difficulties together. Friendship stories can show how friends support each other in different situations.
