Yes you can, but only once. I found the following in the FAQ section (http://www.girlsaskguys.com/faq/account):
We do allow each member ONE username change. Please contact us and provide your desired username (with 3 alternates, just in case) and we'll make the change for you.
Note: We ask that Moderators not change their usernames. Moderators may relinquish their Moderator status and receive a username change then.0
