Do you bolt, warn, or hope they're deep sleepers? (A question about flatulance and intimate nights.)

We’ve all been in that situation. It looks like you’re going to score a hottie, but your guts are acting up! When you seal the deal but know you’ll probably be farting in your sleep, do you pull yourself away and drive home after, warn them that you might be sleep-farting (slarting?), or simply count on your body to come through and try to tire them out so they sleep through it? This could make or break the memory of a great night or the start of a relationship!
