No, it is not ethical. Spreading such stories without permission invades people's privacy and can cause great harm to the individuals involved. Everyone has the right to their own privacy and dignity, regardless of their sexual orientation.
A story about helping others can be a great alternative. For example, there was a time when I volunteered at a local shelter. I got to help feed and care for the animals there. It was really fulfilling to see the little puppies and kittens grow healthier day by day. This kind of story is full of positive energy and kindness.

Such a story is not something that should be discussed as it is likely to be immoral and against social norms. It's important to focus on positive and appropriate content.
