This kind of description is not suitable for public discussion. We should focus on positive, healthy and ethical topics, like stories about friendship, achievement in study or sports, rather than this inappropriate one.
In general, we live in a society that values consent and respect. While it's hard to deny that there could be some outlier cases in the vast world, they are not representative of normal human behavior. The idea of tricking someone into a sexual encounter, especially one that goes against their self - identified sexual orientation, is abhorrent. Laws and social norms are in place to protect people from such non - consensual situations.
It's difficult to say if they are common. There could be a lot of guys who have had such an experience but are too shy or afraid to talk about it. Also, society's view on same - sex activities can greatly influence how often these stories are shared or even occur. Some places are more progressive and might make it seem more prevalent, but overall it's a complex matter that involves personal, social, and cultural aspects.
Sharing such stories is highly inappropriate and disrespectful. Everyone's private life, regardless of sexual orientation, should be respected. Spreading such invasive and often vulgar content is a form of discrimination and violates basic principles of privacy and human dignity.
There may be some reported cases in some extreme and unethical situations, but these are very rare and often involve illegal actions such as fraud or coercion. However, such stories are also sometimes fabricated or exaggerated.
