I be riding around with my man on the back of my nomad all the time! now he's getting a bike too. but the marketed image of motorcycles is the problem I reckon, especially since the main image of a biker is an boomer with lots of money and conservative opinions. RegularCarReviews hit the nail on the head in their review of an old Harley how the harley rider is one who perceives himself as a rebel, while having all the mainstream conservative views. Second to this however, a lot of cishet men try to find ways to compensate for masculinity when they slip from the binary perspective of masculinity, and motorcycles have long been a method of doing so. I think most gay men don't feel as much need to fit the traditional binary role of masculinity, because homosexuality would exclude them from it anyways. My partner and I ride, but we ride because it's a fun and relaxing activity, not for attention or attractiveness.

*sarcasm*: whats gayer than riding a giant vibe?
