Yes, there are. However, it's important to note that these might be misinterpretations. For example, in some cases of hazing or dares in a non - sexual context, actions could be misconstrued and then turned into such stories. But the idea of a straight guy engaging in such an act in a sexual sense may be more of a salacious rumor.
The harm is multi - fold. Firstly, it invades the privacy of the so - called subjects of the story. Secondly, it spreads false and often sexualized information that is inappropriate in a civil society. It can also lead to the stigmatization of individuals who may be completely innocent. This kind of gossip - mongering is not only unethical but also can have long - lasting negative impacts on people's lives.
We should focus on positive, healthy and respectful topics within the LGBT+ community, like their achievements in various fields, rather than such vulgar topics.
