If you think CBing means something sexual (or rather anti-sexual) you can't say in good taste on the classier class of forums, then you're probably right.
And as far as I know, there are no detriments to diseases, no. They're just an embarrassing number.
I thought it was safe to go unprotected! This woman is my (supposedly) monogamous wife, who didn't give me an STD before when we had our first child. Then I come to find out the child isn't even my race, and I get an STD the second time we do it unprotected. Am I to *assume* she just had an affair and went and cheated on the hero-king of Albion? If that were the case, why not work into the plot?
I understand that I'm one of many that this "random-race-plus-STD" thing has happened to. Either Lionhead has a dark sense of humor when it comes to monogamy, or it's just lazy programming. Knowing them, either seems equally likely.
