Research shows that people only use condoms during oral sex about 10 percent of the time, says Herbenick. So, yeah, realistically we know you're probably not going to adhere to this one. But just know that ideally the safest sex practice would be to use a condom or dental dam during oral sex, and that's really your best defense against STIs and HIV. Flavored condoms or flavored lubes can make this a little more appetizing, says Chase, but you might have to experiment to find one you really like.
Remember: Just because most people aren't using protection for oral sex, that doesn't mean you should forgo it or feel silly for requiring it. It's your body, your decision, and your risk. The ~safe~ thing to do is use a condom.
