From what I've seen, there is no single platform/community that's centred around LGBTQ+ friendliness (like e.g. blahaj.zone for lemmy), but I've definitely seen some creators from spectra.video and pony.tube in my feed that should fit the bill.
I hate how if you search trans on peertube (at least on .wtf) it’s straight up porn, like I’m tryna find relatable content, not wank off
You can try filtering out NSFW stuff and look only on specific instances, on Desktop, the filter settings after a search are accesible in the top right and have options here:
Besides that, while I really respect PeerTube.wtf and give them money on LiberaPay for a reason, even though I have since created my own instance, they definitely go with a very permissive style of content on their platform, which is good in its own right, but could maybe not be what you are looking for ultimately. I'm gonna be shameless in promoting my own instance there (but others exist, too, of course), am quick in accepting signups, and I try my best to filter out creators/instances that are focused on porn, conspiracy theories, cryptobro content, etc.
(As an aside: sadly, there were some who cross-pollinated legitimate, often LGTBQ, content with their own jerkoff sessions and porn to such a degree, I ended up erring on the site of caution and muting their stuff, which left a bitter taste in my own mouth, because their other stuff seemed to be interesting and legitimate. This as a PSA: Don't just use a separate channel, better use a separate account for your porn content on PT, as of writing and to my knowledge, there's no proper moderation tools for admins to mute just your porn channel, muting seems to only work by user account or by muting a whole instance, creating a bit of a dilemma for instances wanting to filter out porn)
