This article will teach you how to reset your Bitmoji avatar so that you can select a different gender.
Steps

Step 1. Open Bitmoji on your mobile device
It's the green icon with the winking chat bubble on the home screen (or in the app tray, if you're using an Android device).
- The only way to change the Bitmoji gender is to reset your avatar. You will lose all custom details (facial gestures, hair, outfit, etc.), but you will be able to select another gender when creating your new avatar.
- You must use the mobile app on an Android device or an iOS device. There is no way to reset your Bitmoji in the Chrome app.

Step 2. Press the gear icon
It's in the upper-left corner of the screen.

Step 3. Press Reset Avatar
A pop-up window will appear, asking you to confirm the action.

Step 4. Click OK
When the Bitmoji avatar has been reset, you will be sent to the Design Your Avatar screen, where you can see the two gender options.

Step 5. Select a genre
Now you can customize the face, hair and outfit of your new avatar with the gender of your choice.
