Adults Who Came Out After Straight Relationships - Dating & Aftermath

Searching for people's personal stories about being in a straight relationship before discovering they were gay. So I want to write a story about that but don't know actually how it works. like do you fake it, is it strong platonic love ? and, without being graphic, how does sleeping together work ? anyways yeah, would be really nice to give your personal feelings during that dating. and how your relationship with the person evolved afterwards. thank you ☺️
