I'm so sorry to say - a slice of cake did such terrible things to me I wouldn't dream of doing it again. But I think we all need to have a massive tango experience to scare us into submission! I'm sorry this is TMI, but especially as you're out all day, from tomorrow until tango days are over, I'd recommend you either wear a sanitary towel or try tissue between your buttocks (!!) and also even changes of underwear because the oil that comes out does not smell pleasant. You may have terrible stomach craps (mine were really noisy too) which leads to passing wind, and farting makes the oil come out! Sometimes involuntarily. I hope you're experience is not so bad. It only lasts a few days x
