I've never seen 2 girls, 1 cup. Don't want to, either. In real life, the worst thing I saw was an elderly woman about 83 who trjpped and smashed her face on the asphalt. She was really bloody due to blood thinners and the fact that head wounds bleed a lot. My mum called 911 and we helped her since she's an EMT and I'm going to be a fire fighter.
I've seen pictures in her medical books of gun shot wounds, burns, lacerations, etc.
I used to watch surgeries on TV.
Hearing about female circumcision always bothered me. That and when the Chinese used to break the feet and make then like 3" or whatever.
A lot of things do bother me because I don't like people getting hurt. Blood and guts don't phase me, though.
