I usually prefer classical books, and don't care about protagonist's gender. The only time i do care is when i want to read about specific topic, for example, related to social issues. Sometimes, i want to get a different perspective, and that does not mean that i can totally relate to a character. When i read a book with a black protagonist, teenager protagonist, etc., i just want to look at things through lens of their experience and struggle. In fact, human problems, drama, struggle have been the same throughout the history, i believe, so I can also relate to male protagonist, trying to figure out who he is, looking for meaning of life, because it's much more common experience than we tend to think

You're welcome:)

If you enjoyed the picture of Dorian Gray, maybe you'll like The skin of Shagreen by Honore de Balzac. It has similar plot. Basically, about a man who found the way to fulfill his desires but has to pay his price for it. I also can recommend Steppen Wolf by Herman Hesse. It's a story about a man in the state of constant inner conflict (he basically divides his personality into "wolf" and "human", balancing on the line between them). The book tells his story of finding himself. It was surreal and fascinating book with a lots of food for thought

Maybe you should try to sort of experiment with genres to find the one you enjoy? If you like enemies to lovers trope, you might like "Pride and Prejudice" by Jane Austen. It's not omegaverse, but it's classical example of enemies to lovers. This book is considered to be classic literature, and i promise, it's not the same as fanfiction. Could you specify what tropes (except for the one you mentioned) and maybe genres you would enjoy reading (even fanfiction)? I could give some advice what book would be similar to that

This book made me fall in love with french literature. And the only book that made me shed a tear
