Gay-themed books written by men/gay men and uplifting and not YA.

Hi everyone!

Hope your day is going well.

I am looking for books written by Gay men with a 'gay' theme. It can be romance or any other genre but coming out should not be its main plot.

The book should involve/revolve around adults and should not be YA.

It needs to be humorous with a positive ending.

Bonus points if it has lots of flirting.

Thanks a ton!
