Looking for bookrecs - demisexual characters who navigate their sexuality

Hi! So I'm reading {Over and Over Again by Cole McCade} and I'm absolutely loving the parts where one of the main characters - Imre - is navigating his sexuality. In this case, he even identified as demi which was sweet to see.

I also loved this aspect in the {All for the Game by Nora Sakavic}. The MMC, Neil was just kinda chilling the whole time, claiming he "doesn't swing," and then BAM! He was swingin' kissing a boy!

So yeah, I'm looking for books with demisexual characters exploring their sexuality with an understanding and respectful partner. I want it to have that kinda hurt/comfort feel, where the character is just struggling with their sexuality and the other helps them navigate it with care and understanding.

Bonus points if the demi character is older and only after years and years he finally gets the relief of understanding himself.

I also really want those tender moments of assurance and understanding between the two guys. Also, it'd be ideal if there's the isolation aspect, meaning that there is not many distracting factors from the story and the MMCs.
