"I have been called a dickless bro and told i have penis envy."

I don't support personal attacks on transgenders, but the "dickness bro" remark isn't wrong. These people need to realize that there's a certain point they can't cross because they're unable to relate with people of their desired sex. I'm fine with a transman who is viewing their clit as a penis, but keep it within the realm of reality where you're still acknowledging what it is and that you're unable to relate with other biological man over their penis.

For the "penis envy" aspect, it's obvious that this person is projecting themselves in the comic and their constant questions about "big dicks" is what's resulting in them receiving that label.

"I'm a writer working on a comic about a character with a BD so i thought i'd scoop up some knowledge to help me better write this character (yeah, having a BD isn't a personality trait, but based on posts i've seen here it impacts life in various ways)."

What type of comic is this person working on because I'm failing to see how having a "big dick" is a needed character trait outside porn based comics. Darth Vader for example had his penis burnt off and that has no bearing on him in the comics and the same applies for any male character no matter the comic outside porn. Hell, Alita from the Battle Angel series is a total cyborg and her having no female parts never once was a factor in that series. Again, a "big dick" isn't a fucking character trait for real comics.
