Intercourse can cause female organ gas. Oral sex can cause air to enter the female which leads to gas. Some kinds of rough intercourse can lead to female organ gas as well.
According to Cleveland Clinic, during intercourse, the sliding motion of the male organ puts pressure on the anus, which lies next to the female organ wall. The back-and-forth action can easily lead to gas pockets that evacuate, also referred to as farting.
Vaginal gas is also very normal. Gas can get trapped in the female organ, so when you reach intercourse peak, the muscles around your genitals get relaxed and may allow a little gas to pass out.
If this occurs persistently, you may need to take an over-the-counter anti-gas medication or have a bowel movement before you have intercourse. You should also ask your doctor to check to see if there is a physical cause that can be solved.
For a more permanent fix to this dilemma, try changing your diet to remove carbonated drinks and foods that are difficult to digest.
