Okay, I feel you on this one. I can’t really speak for the Tumblr community, but the Twitter community has this a lot. I don’t think it will be much different because people are people. 60% of my characters are dudes, but the good 40% of gals just need a little push into the right direction. Once you’re settled in a fandom or rpg, plots are a guarantee. And of course, ships are fun. They’re cute, wholesome and angsty and it helps you to stay motivated when writing for said character but honestly, don’t make muses for shipping. Stop it, it’s the law from now on. Shoo.
