The Centers for Disease Control and Prevention (CDC) want to know even more about men who have sex with men. Whether you’re gay, bi or questioning, a new online survey has been launched – the largest of its kind – asking questions that will help researchers seeking new ways to fight HIV, AIDS and other STDs, and to better understand men’s sexual health.

It’s called Sex is the Question. It’s private. It only takes a few minutes to answer. And it even makes a donation to the It Gets Better campaign.

The survey also provides feedback. Once it’s completed, you’ll be able to compare answers with others, and you’ll even receive educational material to help inform you about sexual health – completely anonymously.

Gay and bisexual men account for more than half of all new HIV infections in the U.S. alone, according to the CDC.
