Yes! Zoosk is a bi-friendly site. When you register new with Zoosk you can indicate that you wish to receive profiles from men and women by choosing "Both".
When you already have an account, you can change your preferences by logging in and clicking on your photo, in the upper right corner. Under "Basic Info" and "Interested In" you will be able to make the changes.
Occasionally, users with older accounts may need to contact us through support@zoosk.com, so we can change the settings for you.
