It’s true that most people don’t practice safe sex when it comes to oral. They take a risk. That’s their right. It’s also true that most people don’t understand how much of a risk they’re taking.
You’re being smart about it. And while many DON’T use protection, there are also some that do. So you’re not alone, just in the minority (unfortunately). It’s reasons like this that we still have such a constant problem with the spread of STD’s. People aren’t protecting themselves enough. If you want to use a condom during a BJ (get a flavored one) then good for you! If you want someone to use a dental dam when going down on you, that’s great too. But you will meet resistance and people will try to talk you out of it because it’s “not as fun” and “doesn’t feel as good”. Ultimately, people don’t want to be bothered with it.
As always, protection is your right and your choice, but be prepared to face people ready to talk you out of it. Especially when it comes to oral sex because too many people are under the impression that if you can’t get pregnant from it, there’s no risk.
That’s ignorant as hell.
