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 )

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(p.s. it's okay if you think these texts are "out of date"--even better!)
