People complain that femboys' bodies are "too masculine."? They are... men, lmao. Even very effeminate men are generally going to retain male anatomy and proportions. Femboys bodies are not supposed to physically pass as women.
The problem is that many people aren't actually looking for feminine male bodies. They want characters who look like women in every meaningful physical sense while still identifying as men and having male genitalia.
A lot of these expectations come from the sexualization and fetishization of women, specifically transwomen and physical femininity itself. The object of desire isn't necessarily just feminine men... It's the fantasy of someone who is from the outside (expression and mannerisms) looks feminine , as well as physically has a body that looks like a woman but with male genitalia, while remaining and identifying as a male.
It's the"trap" factor once again, and the shock element of "that's actually a man" that they want, and I don't need to tell you why those standards and unrealistic and forced portrayals, whether in real life or fiction, are harmful and unattainable for feminine men, and why those portrayals are getting a lot of hate from the trans community.
You are not portraying too masculine femboys if you portray what realistic effeminate cis man bodies look like, while it being biologically plausible and achievable for men. They are still feminine. They can still be short, slim, and petite and soft-featured. They can have a small waist, softer thighs, small hip definition, and still be feminine without having proportions that are indistinguishable from a thickass woman with childbearing hips. Feminine men don't have to be tall, muscular, broad, or hairy to be recognizably male.
It would be really nice to see that's all :3
Again, it's your art, and this is an adult fantasy game at the end of the day. Do whatever you want! I've said everything I wanted to say about this topic, so I'll leave it there, and this will be my final comment on this aspect and the overall game.
Have a great day, RadLord :)
