Right now, I started reading a book called "It Gets Better". I would definetely reccomend it! It started with the It Gets Better Project, which I believe was a bunch of videos people would post to YouTube about their experiences with bullying and coming out. The book is a collection of stories that adults tell about their teen experiences in their struggles with coming out. Its really great and some of the stories are heartwarming.
Here are some books: The velvet rage by Alan Downs Denial by Jonathan Rauch 10 smart things gay men can do to help find real love by Joe kort In other words by d.b. Reynolds
For young and not so young adults, try Geography Club by Brent Hartinger, or anything by David Levithan.
