There could be stories about a cute feminine twink who is really into fashion. For example, he might start his own small fashion blog and share his unique style ideas with the world. Through his blog, he makes new friends who also love fashion and they all go to fashion shows together, creating a positive and friendly community.
In the movie 'Love, Simon', there are characters that break stereotypes. Although not exactly a 'twink' in the traditional sense, they show that boys can be sensitive and have a more feminine side while still being strong and positive characters. They are characters that are true to themselves and inspire others to accept themselves as well.
In ancient myths from various cultures around the world, we find stories about the afterlife, the relationship between humans and the divine, and how to live a virtuous life. There is no room for such offensive 'guy sucks cock stories' as they go against the very essence of what ancient myths were created for.
I'm not aware of any positive or appropriate stories with such a vulgar concept in mainstream literature. Literature usually focuses on more positive, moral and inclusive themes.
Rather than delving into such inappropriate stories, we should encourage a society that promotes love, respect, and positive interactions within marriages. There are so many wonderful aspects of married life to focus on, like mutual support and shared dreams.
