"Yep, and thanks to that crystal you are too, honey." Buck says. "It's a focus of stuff that makes up the world, and it's gay stuff. Makes straight guys gay while wearing it, women into men who like men while wearing it, et cetera, and then lets them add more gay to the world or return stuff to the baseline."
He sits up a bit, flexing in a way you can definitely appreciate. You didn't feel that different offhand, but even a hint of sexuality and it's suddenly so obvious. "Chaz, I'm basically the guardian of that unbreakable nugget. I deploy it to guys who could stand to be heteroflexible, recall it when it's lost, patch up reality for best results, that sort of thing. If you wanna make yourself stay gay or bi with or without the rock that's fine, but I'm here to help you and a few others wake up their inner homo. Been doing this since humans were designed and I'm still friends with most of those ghosts."
"So what, you're my guardian gay-ngel now?" you poke, suddenly feeling a tenting sensation in your pants at the idea of your best friend bringing an unknown amount of power to fun experimenting.
"You're like...thirteenth guy to make that joke, bro." Buck says with a roll of the eyes and a mock frown that fades into a smile. "So yeah, jig's up but I'm the same guy you've known for years, just outed. Sure lowers a lot of barriers to getting to know all of me. You can try out the off switch by the way, just wanted to have that impact of seeing me in a new light."
You experimentally take off the necklace, and suddenly Buck seems like Buck as usual again as you go back to being close enough to straight. You put the necklace back on, because it makes Buck seem actively sexier instead of just a recognizable friend attractive in the abstract. Maybe a bit less 'abstract' when you compare the experience of a thing that makes you explicitly gay instead of just questioning isn't that different after all...
"I'm interested in knowing more." you say, walking up. "Keep talking, or get handsy?"
"Both," Buck confirms, getting way into your personal space. "both is good. C'mere, I know a dive with backrooms near this park where we can hang out. We don't need to go clubbing on an empty stomach, I'll buy us dinner if you're hungry."
"Sure, sure." you follow along, very closely. You're holding hands with him just because there's a slightly different tinge to doing so now.
A street away is the Confirmed Bachelor, a gay bar and sex shop loitering in a nondescript grey part of town with some tall fences concealing a more festive outdoor area. Buck buys some generic salad and a burger for you, glancing at the provocatively dressed staff with the experience of an old hand but the excitement of sharing it with a new friend. You find yourself staring at men of assorted shapes and sizes, realizing a depth of complexity and different ideals of beauty the same way you used to see hot women. Twinks, bears, cubs, chubs, silver foxes, otters, twunks, wolves, Buck rattles off what's archetype, what's stereotype, and what's just type between bites of lettuce and tomato. It's chitchat, but pretty similar chatter to your usual dynamic just with a lot more advice on what you can find in pants and how to use it. The low hum of background chatter and clacking drinks is enjoyed atmospherically along with your burger and soda. You do suss out that Buck wasn't kidding about being a secret admirer and finds you attractive. You're not really sure if it's a date or not. Either way, Buck is quite clear the cruising environment and his personal stance allows being friends with benefits or even going romantic if you're feeling committal.
After dinner, Buck pulls you through to the more overtly sex shop rooms of the establishment, and the back rooms where people are free to play.
"Okay, welcome to being gay." Buck says more formally with a soft clap once you're ensconced in a semi-private area with him. You glance down at the gaying gem he's guardian of like the magic rock was just for sitting pretty or something. But Buck keeps talking. "Atmosphere and options are one thing, but if you wanna experiment I'm right here."
"I'm game." you say.
