It is a serious matter. What would you do, if you mistakenly pollute on your first date with a lady you really admire.

It was so loud, that it couldn't be denied.
You couldn't control it.
How will you feel and what will you do?

Normally without the date, it's immoral to fart in the midst of plenty people, it's lack of ethics that makes you have a feeling something terrible is about to erupt and still tend to remain at that position, it's not a turn on I'd say.
