Hey... Just letting you know... I’m not trying to be rude.
This game doesn't support playing as a female protagonist, so what you're asking for isn't possible here, even with a mod. If you're specifically looking for games where you can play as a female character in erotic scenarios, I’m happy to help you find some recommendations.
If you're looking for more freedom in expressing yourself, including erotic roleplay as a female, I suggest checking out VRChat. You can customize your avatar however you like and connect with others in a much more open environment. There's no limit for how you wanna do your erotic roleplay.
Whatever you're into, no judgment here. Just a reminder to keep things respectful for everyone.
