I like a very specific category of book; It is gay boys figuring out that they like each other preferably in high school and there may be some sexual scenes.
My favorite book of all time is They Hate Each Other by Amanda Woody. Some others I enjoyed were
A Boy Worth Knowing by Jennifer Cosgrove
The Dangerous Art of Blending in by Angelo Surmelis
How Not to Ask a Boy to Prom by S.J. Goslee
And
Been Here All Along by Sandy Hall
