Definitely not. It involves inappropriate and private sexual matters that violate social ethics and good taste. There are so many other positive things to talk about like hobbies, achievements, and cultural experiences.
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.
Well, communication is key. You need to be able to talk openly with your partner about what you're comfortable with and what you're not. And of course, you should be in a legal and appropriate relationship. Another important aspect is understanding your own feelings and boundaries, and not doing something just because you feel obliged.
Sharing such a story is completely inappropriate and unethical. It involves vulgar and inappropriate sexual content that goes against moral and social norms.
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.
