Girls advice needed please.?

Girls ok the was i feel is farting is a natural bodily function and i want a girl to feel free to let rip as loud and proud as she needs and as often as she needs. The way i feel is i don't don't want the poor girl holding it in and feeling all bloated, sick and uncomfortable the way i feel is i don't want the poor girl holding her wind in i want her just to let rip. So how do i show her that its honestly ok for her to fart and convince her to do it? Thanks
