Looking for realistic gay coming-of-age books!

Hello, everyone. 😊

I am looking for book recommendations. I'm looking for stories about gay (male) teenagers coming of age and exploring their sexuality that are written in a realistic way.

I've read and loved the following books:

• Heartstopper webcomic
• Aristotle and Dante Discover the Secrets of the Universe (and its sequel)
• Simon vs. the Homo Sapiens Agenda

To give you a better idea of my taste, I also really enjoy these TV series in the same genre:

• Skam season 3
• Young Royals
• Heartstopper series
• Rykter on NRK
• A Danish mini-series called "One of the Boys"

Any suggestions would be much appreciated! Thanks!
