I remember watching a show last year where a doctor from the CDC was discussing oral sex and STDs. She said that you can get every STD there is from oral except crabs. Those travel from hair to hair. Of course, it depends on if you have facial hair and pubic hair, which we have neither.
So, what's the point of being "safe" when engaged in intercourse, if you're going to pass along the germs during oral anyway?
That's our opinion from reading and talking to sex experts (medical field).
