Holding contained by farts?

For all the girls out within...Do you hold in your farts when you are around your boyfriends or other individuals or do you let them rip? Ok, I looked up the components of Malodorous Gut Wind, and I discovered that the component of a fart that cause it to exude an undesirable odor is the hydrogen sulfide.
Here are some exerpts from the Material Safety Data Sheet (MSDS) for hydrogen sulfide:

Based on what it can do you people around you if you consent to it out...I don't think its a perfect idea to maintain it INSIDE you!
