Is the "first fart in a relationship" always done by the male?

No, in my current relationship I absolutly love my boyfriend, but i had gas building up really bad and he could tell i didnt feel good and I told him that i had gas and he basically MADE me let it out lol. And also He has seen me pee, but how long do you think you have to be together before you can take a SH!t in front of each other?
