Using the BBWDesire app is easy and straightforward. First, you need to download it from either Google Play or Apple App Store. Once downloaded, open the app and create an account by entering your email address or phone number as well as a password for security purposes. After that, you will be asked to fill out some basic information about yourself such as age range, gender preference etc., which helps in finding potential matches based on your preferences. You can also add photos of yourself so other users can get a better idea of who they are talking with before messaging them directly through the app's chat feature. Additionally there are various search filters available which allow users to find their ideal match quickly and easily according to criteria like location proximity or interests shared between two people; this makes it easier than ever for members of all backgrounds looking for love online! Finally once matched up with someone compatible simply start chatting away - getting know each other more intimately over time until eventually deciding if meeting up in person would be something both parties want!
