Does anyone else wish they could search LGBT terms on tumblr without just ending up with a bunch of bad porn?
Yes. It's pretty much why I don't look in the LGBTQ+ tags of Tumblr. I would rather find something nice.
The bisexual tag is improving on tumblr. Though sometimes it feels like it trades porn for biphobic posts.
Tumblr is the absolute last place (well... maybe it's in front of Westboro Baptist) that I'd go for a reliable definition on any LGBT terms.
You could use google, for example, or another search site, and fine tune your search. -you can enter the site you want to look on: site:___ -then you can enter your keywords -you can exclude terms with a minus directly in front of it -you can look for exact terms in "" You might just keep your search terms seperated by spaces, enter them, and you can then fine tune your results with more exclusions, for example.
