The stereotypical Twink is often considered quite effeminate. Conversely, a Hunk is thought to be big and butch. This would suggest that a Gay Twunk is a more masculine acting Twink. But stereotypes are just oversimplified ideas of a person.
What's certain is that a Gay Twunk has put in some serious gym work. Moreover, he’s guzzled gallons of protein. And not just that sort.
Unlike a Twink, a Gay Twunk is not content to accept the body that nature and youth have gifted him. He’s driven. And he’s passionate. Even if this might only be about himself.
