twitter friends: what are modern "classics" of gay male literature (thinking 1960-present day) that you think everyone should read?

(p.s. i love crowdsourcing. thanks, friends https://abs.twimg.com/emoji/v2/... draggable="false" alt="🙂" title="Slightly smiling face" aria-label="Emoji: Slightly smiling face">)

to be followed up with: what classics of gay theory (and queer theory) that focus on gay male desire/homosexuality do you think everyone should read?

(p.s. it& #39;s okay if you think these texts are "out of date"--even better!)
