You like a woman to be nice and wet where it counts? This wetness, also known as vaginal fluid or secretion, ensures that everything's lubricated and slides smoothly without causing any injury. So it's actually a good protection.

But be aware: vaginal fluid can contain HIV and hepatitis-viruses type B.

Sometimes it's not just vaginal fluid that makes a woman wet. There are also discharges that can contain disease organisms without the woman being aware of it. So you can pick up gonococcus, chlamydia and trichomonad pathogens holen. And of course there can also be blood in the vagina. From minute injuries, or when the woman has her period.

So when you're having sex, it's better to use a condom.

If you're licking the woman (Cunnilingus) and want to avoid contact with vaginal fluid, you can use a thin latex sheet (also called Dental Dams). They're available in sex shops - in various flavours if you want.
