OP is making the same old mistake of conflating the risks of oral sex to the wrong audience. This is a forum of people that frequently engage in unprotected oral sex. Almost weekly we do it. Yet how many of us have caught an STI by doing that?

I mean if he went to a highschool and said the same thing, the effects would've been a lot more effective. Not here.

Don't get me wrong, I'm not writing off the risks. I know very well that catching something through your mouth is a lot easier than catching it through your genitals, simply because we put a lot more things into our mouths than our genitals. We use it to eat. It's an orifice made up of very soft tissues encasing a set of "tools" designed to cut and incise. Compare the chances of getting a cut in your mouth vs getting a cut in your genitals, it's chalk and cheese really.

Once you understand this aspect of the risk, then you would understand how to minimise the risk of catching anything through your mouth. Stats are just stats, they don't take into account this factor, but that shouldn't stop you from being smart about it.

One thing I do agree with OP is about girls who do CIM. CIM is actually a higher risk of STI than BBFS because of the above reason. And I don't think girls are stupid, they probably know the risks too, and probably avoid BBFS due to the pregnancy risk.
