4chan has a lot of "twink 4 twink" types for some reason, but irl they're not that common, at least in my area. I have big muscles, lots of chest hair, I'm tall, and I have a big cock, and I can pull almost any twink on grindr that I want. I'm catnip for catboys. I think most "twink 4 twink" guys are tops so it wouldn't work out anyway.
just don't tell them that you're bi. you can be exploring, or newly gay, or just really fucking horny, or almost anything but bi. gays are very suspicious of bi guys.
