Understand important health issues for gay men — from sexually transmitted infections to depression — and get tips for taking charge of your health. Men who have sex with men are at increased risk of contracting HIV, the virus that causes AIDS, as well as other sexually transmitted infections, including gonorrhea, chlamydia and syphilis.

To protect yourself from sexually transmitted infections:

• Get tested and have your partner tested. Don’t have unprotected sex unless you’re certain you and your partner aren’t infected with HIV or other sexually transmitted infections. Testing is important because many people don’t know they’re infected, and others might not be honest about their health.
• Use a condom or other protection. Use a new latex or polyurethane condom every time you have sex — especially during anal sex, but ideally during oral sex as well. Use only water-based lubricants, not petroleum jelly, hand lotion, cold cream or oils. Oil-based lubricants can weaken latex condoms and cause them to break. Don’t share sex toys, and keep them safe by protecting them with a condom and cleaning them before and after every use.
• Be monogamous. Another reliable way to avoid sexually transmitted infections is to stay in a long-term mutually monogamous relationship with a partner who isn’t infected.
• Consider the drug Truvada. In July 2012, the Food and Drug Administration (FDA) approved the use of the drug Truvada to reduce the risk of sexually transmitted HIV infection in those who are at high risk. Truvada is also used as an HIV treatment along with other medications.

Tackle depression:

Gay men and men who have sex with men might be at higher risk of depression and anxiety. In addition, youth who identify themselves as lesbian, gay, bisexual or transgender might have a higher risk of depression and attempted suicide. Contributing factors could include social alienation, discrimination, rejection by loved ones, abuse and violence. The problem might be more severe for men who try to hide their sexual orientation and those who lack social support.

Left untreated, depression can lead to risky sexual behavior and a downward spiral of emotional, behavioral, health, and even legal and financial problems. If you think you might be depressed, talk to your doctor or seek help from a mental health provider. If you’re reluctant to seek treatment, confide in a trusted friend or loved one. Sharing your feelings might be the first step toward getting treatment.

Address body image concerns:

Gay men are more likely to experience body image problems and eating disorders, such as anorexia and bulimia nervosa, than are their straight counterparts. One potential explanation is that gay men identify with the cultural value placed on an ideal — yet often unattainable — body image. Gay men might also be more likely to view their bodies as sexual objects, which can lead to dissatisfaction and poor body image. If you’re struggling with body image concerns or an eating disorder, get help. Talk to your doctor or a mental health provider about treatment options.
