I put “straight” in quotes because, sitting around, dicks out, perhaps polishing a penis that does not belong to you, sounds pretty far left of strictly hetero to me, but it’s also increasingly clear that there’s infinite space in the gray area between a Kinsey 0 and a 6. A recent GQ trend piece explored the phenomenon of “straight” masturbation clubs, and I’ve seen online ads for such clubs that specifically target “straight” guys and more or less rebuke gay ones. Or maybe connectivity has made this phenomenon more accessible and easier to gauge and discuss? Ya never know with these things.
It does seem like more straight-identified guys are getting into mutual masturbation with other so-called straight guys these days.
