>>1080This is what aspiring gay smut writers would pass around back in the day:
https://www.squidge.org/~minotaur/classic/eroc.html IMO it veers a little too hard into "teh yaois must be realistic!" for me, but it's informative. I hold him in higher regard than other Gay Men With Opinions About Fujoshi because he actually wrote slash fic and entertained Q&As (
https://www.squidge.org/minotaur/mqa/browse.html). He died back in 2009. :c
My personal advice is to read a lot of smut and make note of what gets you going, then go back and examine the prose. For example, with Ao3 it's easy to just pick a tag for any kind of sex you want to study. Go read a bunch of blowjobs in a popular ship you like (or are at least familiar with), then think about why some of them were hotter than the others when it's all just words describing the same act. You could also read original erotica but I will be real I do not give a fuck about reading OCs boinking unless it's incidentally to my taste in lit and I feel like around fujochan we are probably all like this?
