Masculinity, camp, and the pressure to pass
Gay and bisexual men get it from both sides. Too camp, and you are a joke, a risk at work, a man some other men will not date. Too straight-acting, and you are accused of internalised homophobia, of 'passing,' of taking the easy road. Both pressures are real. Neither one is a personality you owe the public. You get to live in a body and a manner that you can stand.
Straight-acting is a market and a shield
On apps, 'masc only' is often a ranking system: less feminine, less Black, less Asian, less obvious. Sometimes it is also how a man stays employed or un-assaulted. Those two uses get tangled. You can protect yourself without advertising contempt for men who cannot or will not pass.
If you only feel desire for a narrow masculine costume, that is your business in bed. If you treat camp men as contamination, that is homophobia with a gym membership. Homophobia, biphobia, and internalised shame names the inside voice.
Camp is culture, not a defect
Camp (wit, extra, theatricality, a walk, a vowel) is one of the things gay culture actually invented and kept. It is not the only way to be gay. It is also not a phase you are supposed to grow out of after you buy a house. What is gay culture? is not a straight-acting brochure.
Some men are camp because they are. Some use it as armour. Some drop it at the office and pick it up at the bar. Code-switching is a skill, not a sin, as long as you are not pretending the office version is the 'real' one.
Roles, bodies, and the same police
The same system that ranks masculinity will tell you bottoms should be small, tops should be hard, bears should be jolly, and twinks should expire at 30. It is all costume drama. Bear, otter, twink, and other body tribes and What do Top, Bottom, Versatile, Vers-Top, and Vers-Bottom mean? are useful until they become a cage.
Body image harm follows the same ranking. Body image, gym culture, and eating issues is the health page.
