When giving (or receiving) oral sex, be aware that hepatitis B, fungal infections and other STDs can be passed on via oral sex and blow jobs. The risk of HIV transmission from performing oral sex is low but it can still happen. If you’re unsure of your partner's sexual past, use a condom.
Mouth infections can also be transmitted via oral sex and remember never to give head when you have a cold sore unless you want to give him herpes!
