DLsite has a for women storefront. It's the R18 BL/TL button on the far right. As for other stuff here on itchio, try this collection: https://itch.io/c/1172106/sexy-mostly-lesbianfemale-protag-games
Thanks for the help. Though, from the looks of things, dlsite probably won't be a viable option for me until I relearn how to read Japanese. There are so few translated options, and the few that are there still have the issue of a powerless, female protagonist. Why is it so hard for a girl to find erotic M4F game scenarios where they can be in charge...?
