You should never feel bad about something like that. Also visual representation (what it technically is lol) matters as much as the ones who goes further.
Either way you are and should be making content which YOU should enjoy first and foremost. There will sadly be always people who say it's not enough, ignore them! If they have time being rude or demanding then they have time to come up with stories themselves. Nowadays if you have an electric device you can easily publish stuff but they don't and go to whatever random artists and expect something WITHOUT even paying for it. Enough ranting about them tho lol.
You should never feel selfish about something that doesn't really harm anyone (in this case it mostly just does homophobes egos lol)
And i myself love "visual representation" more than the more detailed one, because: Everyone in that community can relate to that it's less likely than an experience which always varies. For example i don't make a big deal out of my attraction or really tell anyone unless they ask and people like me are less likely to be fazed by lgbtq+ related discrimination than people who are more open about it. Not saying that it's okay or shouldn't be addressed but in visual representation it's the community that is the main point which everyone can relate to and the specific representation one is more about a certain struggle which some can and some can't relate. Both valid just expressing my opinion ^^
Also it's nice for those who deal with those problems or read about them have stories where they relate to without: reminding them of real life, that are not over the top or just chill in general.
Also those stories are also normalizing the fact that it shouldn't matter (at least not negatively) which gender you are attracted to or what you identify yourself as. So those stories are in some way showing the "end goal" if you understand what i mean lol
Either way any realistic representation matters even the unintentional ones (which i count you in. Means you just do it because you want to not because you feel you need to which is valid and should always be the case about many other stuff in general too!).
And if you feel you want to just create stories you like and the way you want then you should! You don't owe us anything so never feel obligated or selfish because you are your own person and don't have to live or work to just please others by neglecting yourself, aka mental health/putting other people's opinion/"needs" before yours, and the way you want to express yourself or your opinions/beliefs in your stories!
Also for those people who i ranted before:
EVERYONE is entitled to have opinions but forcing them onto others is a no go and you can always find someone else who fits your liking more and does what you believe in passionately so don't waste your time trying to change someone's opinions or the way they want to write, express themselves and so on instead push and help people you like. This way no one gets hurt/harassed and you don't come of as a rude controlling person.
I hope i made myself kinda clear my english can be really bad lol if anyone is confused about a sentence then tell me and i try to word it better ^^
I hope this comment was not too negative if it was i can delete it ^^
For now take care and Happy Pride be proud of who you are :D
