Honestly, a lot of why i prefer looking at anime girls over real women in terms of sexy art comes down to a couple reasons:
1. I know no one is being exploited behind the scenes because they don't exist
2. They can do impossible things real women can't do that are at the very least interesting to see
3. I'm not contributing to thottery
4. I have a bad habit of imagining myself in committed relationships with real women and my brain doesn't do that annoying depressing shit with anime girls.
