Aren't those conferences targeted at adults? Is there some assumption in english speaking countries that the average adult is offended when he hears about sex?
Because it sure as hell doesn't hold true in most non-english speaking countries...
I think the assumption generally is that some women will feel uncomfortable with a sex jokes in an audience where they tend to be a small minority. My experience as a man is that women in groups are at least as prone to telling dirty jokes as men, but I can understand that if you're one of a handful of women in a room full of men it might feel quite different.
As the IT guy in a variety of medical offices who's known for being pretty laid back, some of the discussions that have happened when I was in the room are filthy. Also, sometimes folks forget I'm in the room.
The most memorable and amusing was the discussion by several women (some busty) of "[flopping them on the counter]", but there have also been discussions of men or parts thereof.
I live in America. It's still unclear if there's a national consensus on women being mainly sex objects with breeding potential rather than thinking, speaking human beings, and thus every woman with a brain needs to be reminded that they're properly understood to be fuckholes. Maybe in your English-speaking country, things are better?
