nah, it is a personal preference (that doesn't match mine) but if it makes you happy, go ahead and write that fic about a skinny hairless twink bottom! dw, fellow trans men also write fics about their personal fantasies that have little to no relevance to me
it is a bit annoying at times that much of transmasc content doesn't match my preferences, but it's a reason for me to encourage those who create the content i like (or create some myself if i cared enough), not to complain about other content (ok mb complain a little to my friends in private), even if i find it weird or cringe
p.s. have read some reblogs and want to add that a fictional character doesn't have to represent the author's beliefs about entire group of people, and depending on genre it doesn't even have to be a thoroughly designed character. it represents what author wanted to write about, not what majority of real people are like or anything else
and if you form your impression on trans men (or any other group of real people) based on fictional characters (even worse if it's from porn) and not real people, then, well. don't, lmao, that's a wrong thing to do.
tl;dr as a grown ass man why should i care about other person's fan fiction preferences, chill
