The last way that one can take care of oneself against STDs is a latex barrier. Latex barriers come in flavors or they come non flavored. The way that this particular method is used is for oral sex. That's when a person's mouth goes on to someone's genitalia. What we do with these is these are a little bit difficult to find, but if you look online, you may be able to purchase these in bulk. The way that they look is like this. And the way that they're used if this is the vulva of the female, it lays over the vulva of the female as so. And as oral sex occurs. It can also be used to cover the anus, with oral sex on the anus if someone would like to do that. And one-time use also. Once they're done. Throw it away into the trash. We don't reuse these ones either. These protect males and females. And if for whatever reason, these particular ones cannot be found, because as I said they are difficult to find, you can use a male condom. Male condoms, bring them all the way down - this is the only time we can use scissors or nails. Break the top of the male condom, and then we bring this down lengthwise, all the way down to the tip. And then you can use this for oral sex. So this is another way for protecting oneself against STDs.
