Thus, giving oral sex may result in STD pathogens passing into the giver's mouth. Receiving saliva is mostly safe. (Which is why kissing normally does not pass on disease.)
So is wikipedia wrong?
It claim man has more danger in recieving oral sex from woman than performaing one?
The vagina is an acidic environment, because of its features. This is so because if the vagina was neutral it would be at a greater risk against pathogens. In some ways it already is. Women are more likely to receive bladder infections than men, the entrance route for bladder infections usually being the vagina.
With men however, the penis is not an acidic environment. I am sure they are at a minutely higher risk for STIs affecting the skin, and possibly for other infections via the urethra. I don't think it matters whether a woman or a man performs the oral sex. I'm sure the risks are entirely based on the anatomy of the recepting partner.
