I don't know if this is quite what you meant, but one of the things I've always appreciated about fandom is that I can roll around in all the vicarious feelings my characters have for each other, and it's incredibly gratifying without being RL messy. Like, in the past, upon occasion, getting RL crushes has been wildly inconvenient, but having fictional vicarious crushes is THE ABSOLUTE BEST and gives me somewhere to put my excess romantic energy without any downsides. :-)
