During the first phase of most romantic relationships, we try to look as desirable as possible, even if that means ignoring some of our bodily urges. Like, letting out a fart, for example. Sooner or later, however, most couples realize that there's no need to blow against the wind and deny their biology, sharing their first fart. Weng Chen, the artist behind The Adventures of Messy Cow, thinks it's perfectly normal, too. To highlight this, she has created a humorous fart guide for everyone who is sharing a bed with their significant other, and it might be more useful than you'd think.
