Kissing
Big on kissing? Prolonged intense open-mouth (French) kissing can increase your risk of contracting a sexually transmitted infection (STI) such as herpes, syphilis, gonorrhoea or hepatitis.
Test Together
Many gay men get infected with HIV or other STIs by their partner.
Gay men in relationships may not be monogamous, and may not know their own or their partner's status.
Get tested at least once a year.
